Million
dollar man: Turing's notebook sells at auction
Computing
pioneer now getting praise he deserves
He's
without doubt one of the heroes of the information age, and now Alan Turing's
work is finally being valued by the world at large, with the computing
pioneer's notebook selling at auction for in excess of a million dollars.
The
52-page notebook, which can make an honest claim to be an historic document in
computing, sold for $1,025,000 (£698,538, AU$1.3m) at Bonhams auction house.
The guide
price was at least seven figures and an anonymous bidder inched it over that
threshold.
Turing's
brilliant but sad life has been celebrated in film recently, and his role in
cracking the enigma code during World War II and his impact on the burgeoning
world of computing is finally being acknowledged.

GLAAD honours film, TV work
MIKE CIDONI LENNOX THE ASSOCIATED PRESS
Published March 23, 2015 - 6:41pm
BEVERLY HILLS, Calif. — Actress Kerry Washington, director Roland Emmerich, the film The Imitation Game and television shows Transparent and How to Get Away With Murder have received stamps of approval from GLAAD.
GLAAD is a U.S.-based group that promotes lesbian, gay, bisexual and transgender presence in the media, and celebrated its honorees at a ceremony here Saturday night.
GLADD president and CEO Sarah Kate Ellis said Scandal star Washington was chosen by the group because, “She’s done quite a bit for the LGBT community and she’s a phenomenal spokeswoman for us. And she’s got our back. And she always has.”
In Washington’s acceptance speech, the actress reminded, “In 1997, when Ellen (DeGeneres) made her famous declaration, it took place in an America where the Defence of Marriage Act had just passed months earlier, and civil unions were not legal in any state. But also remember that just 30 years before that, the Supreme Court was deciding that the ban against interracial marriage was unconstitutional.
“Up until then, heterosexual people of different races couldn’t marry who they wanted to marry either. So, when black people today say that they don’t believe in gay marriage … the first thing that I say is, ‘Please don’t let anybody try to get you to vote against your own best interest by feeding you messages of hate.’ And then I say, ‘People use to say things about that about you and your love.’”
The German Emmerich is perhaps best known for producing and directing the 1996 blockbuster Independence Day, as well as the 1998 remake of Godzilla and 2004’s The Day After Tomorrow. Now openly gay, Emmerich said he long kept his homosexuality private because he didn’t want to be limited to making only films with gay stories, as had happened with other directors in Germany.
Emmerich’s gay-themed historical drama Stonewall will be released later this year. And Emmerich said Independence Day 2, due next year, will feature an openly gay character.
More GLAAD awards will be handed out at a ceremony in New York May 9.
Among last night’s other honorees:
Outstanding Film, Wide Release: The Imitation Game
Outstanding Drama Series: How to Get Away with Murder
Outstanding Comedy Series: Transparent
Outstanding Individual Episode (in a series without a regular LGBT character): Identity Crisis — Drop Dead Diva
Outstanding TV Movie or Mini-Series: The Normal Heart (HBO)
Outstanding Daily Drama: Days of Our Lives

Hello,
I just signed the petition, "British government: Pardon all of the estimated 49,000 men who, like Alan Turing, were convicted of consenting same-sex relations under the British "gross indecency" law (only repealed in 2003), and also all the other men convicted under other UK anti-gay laws.."
I think this is important. Will you sign it too?

English mathematician and logician, Alan Turing, helps crack
the Enigma code during World War II.
By: Linda Barnard
Staff Reporter, Published on Tue Sep 09 2014
Benedict Cumberbatch says the goal of The Imitation Game
is to introduce brilliant mathematician and computer pioneer Alan Turing to the
world, a man who was hounded to suicide because of his homosexuality, despite
saving millions of lives during the Second World War with his secret military
work.
“If we do anything right with this film it is to bring Alan to
a broader audience of people who hadn’t known him in all his complexities and
brilliance before, and encourage people to investigate that further and
understand him fully, and celebrate him and remember him the way he should be
remembered,” Cumberbatch told a TIFF media conference Tuesday afternoon.
The Imitation Game is already generating Oscar talk at
TIFF, ahead of its Canadian Gala premiere Tuesday night.
Cumberbatch plays Turing, a genius mathematician and puzzle
solver hired by the British military to break Nazi codes in the 1940s that
showed pending attacks. Cracking the complex cryptography, made even more
impossible because it was changed every 24 hours, eluded Britain’s MI6.
Matthew Goode (Watchmen) and Allen Leech (Downton
Abbey) work alongside Turing, as does Keira Knightley as Joan Clarke, a
brilliant puzzle solver who becomes briefly engaged to Turing.

Benedict Cumberbatch and Keira Knightley talk about The
Imitation Game at a news conference on Day 6 of the Toronto International Film
Festival.
“It’s a spy thriller, a war movie; it has two love stories.
It’s a human rights, a gay rights (story). It had all these layers,” explained
Norwegian director Morten Tyldum, whose Headhunters was at TIFF 2011.
Tyldum said Turing was a mystery to him at first and he hoped
to introduce him to the audience in similar fashion, revealing the character
onscreen as “a puzzle.”
Very little was known about him for years because Turing’s
military records were top secret. Even when he was on trial for indecency in
1952 (homosexuality was still considered a crime, and he was convicted and
chemically castrated) Turing never breathed a word about his war work, said
Tyldum.
“Even then he didn’t come out (with) all that he did. He kept
the secrets,” said Tyldum, calling him “one of the best British spies ever.”
Clarke knew about Turing’s sexuality and kept his secret,
aiding the socially awkward Turing to work with a team rather than isolating
himself. He in turn helped nurture her work by recognizing her brilliance.
“I think it’s a great friendship and a meeting of the minds,
and I think they did love each other, not in a sexual way but as friends,” said
Knightley.
Knightley also said she suffered her first injury on a set
while filming The Imitation Game, pulling her quad muscle while running
through a door.
“I’ve done a lot of action movies and you wouldn’t expect this
one to be the one where I actually got injured,” she said.

--------------------
In the spring of 1941, Joan Clarke developed a close
friendship with her Hut 8 colleague Alan Turing. Clarke and Turing had actually
met previously to working at Bletchley Park, as Turing was a friend of her
older brother. For a time, they became inseparable, Turing arranged their
shifts so they could work together and they spent many of their leave days
together. Soon after this blossoming friendship, Turing proposed marriage and
Clarke accepted. However, devastatingly for Clarke, a few days after the
proposal, Turing told her [2]:-
... to not count
on it working out as he had homosexual tendencies.
Turing expected this to be the end of their affair, but
Clarke was undeterred by his declaration, and their engagement continued. To
understand her decision to continue with the engagement following his
disclosure, it has to be made clear that during this period in history,
marriage for many women, was considered a social duty and it was not necessary
that marriage should correspond with sexual desires.
Clarke was formally introduced to Alan Turing's family and
vice versa, he gave her an engagement ring, although she did not wear it when
in the Hut, choosing to keep their engagement secret from their colleagues.
They talked of the future and Turing told her of his desire to have children.
They shared many interests, both were keen chess players and, as Clarke had
studied Botany at school, she could become involved with Turing's life long
enthusiasm of the growth and form of plant life. When Turing wrote his account
of the Enigma Theory for the use of new recruits in Hut 6 and Hut 8, (known at
Bletchley Park as "Prof's book") he used Joan Clarke as his 'guinea
pig' - she had to read and trial it, checking that it was understandable for
them.
In the late summer of 1941, following a holiday in North
Wales, their engagement ended by mutual consent, because of Turing's belief
that the marriage would be a failure because of his homosexuality. Clarke was
to remain friends with Turing for the rest of his life. Years later, after they
had both left Bletchley Park, Turing revealed in a letter to Clarke that he
"did occasionally practice" his homosexuality and that he had been
"found out". Homosexuality was illegal at this time, with
imprisonment or chemical castration the punishment for offenders. In 1952 in
Manchester, Alan Turing was convicted of "acts of gross indecency"
following admission to a relationship with another man. In his defence, Turing
said he did not consider he had done anything wrong. As a result of the
conviction, Turing was given oestrogen injections for a year, and shortly
afterwards Alan Turing committed suicide.
--------------
Winston Churchill said that Turing made the
single biggest contribution to Allied victory in the war against Nazi Germany.
From Wikipedia: Alan Mathison Turing, OBE, FRS (/tjr/
tewr-ing; 23 June 1912 7 June 1954) was a British mathematician, logician,
cryptanalyst, philosopher, pioneering computer scientist, mathematical
biologist, and marathon and ultra distance runner. He was highly influential in
the development of computer science, providing a formalisation of the concepts
of "algorithm" and "computation" with the Turing machine,
which can be considered a model of a general purpose computer.[2][3][4] Turing
is widely considered to be the father of theoretical computer science and
artificial intelligence.[5]
During World War II, Turing worked for the Government Code
and Cypher School (GC&CS) at Bletchley Park, Britain's codebreaking centre.
For a time he led Hut 8, the section responsible for German naval
cryptanalysis. He devised a number of techniques for breaking German ciphers,
including improvements to the pre-war Polish bombe method, an electromechanical
machine that could find settings for the Enigma machine. Winston Churchill said
that Turing made the single biggest contribution to Allied victory in the war
against Nazi Germany.[6] Turing's pivotal role in cracking intercepted coded
messages enabled the Allies to defeat the Nazis in several crucial battles. It
has been estimated that Turing's work shortened the war in Europe by as many as
two to four years.[7]
After the war, he worked at the National Physical
Laboratory, where he designed the ACE, among the first designs for a
stored-program computer. In 1948 Turing joined Max Newman's Computing
Laboratory at Manchester University, where he assisted development of the
Manchester computers[8] and became interested in mathematical biology. He wrote
a paper on the chemical basis of morphogenesis, and predicted oscillating
chemical reactions such as the BelousovZhabotinsky reaction, first observed in
the 1960s.
Turing was prosecuted in 1952 for homosexual acts, when
such behaviour was still criminalised in the UK. He accepted treatment with
oestrogen injections (chemical castration) as an alternative to prison. Turing
died in 1954, 16 days before his 42nd birthday, from cyanide poisoning. An
inquest determined his death a suicide; his mother and some others believed it
was accidental.[9] On 10 September 2009, following an Internet campaign,
British Prime Minister Gordon Brown made an official public apology on behalf
of the British government for "the appalling way he was treated." The
Queen granted him a posthumous pardon on 24 December 2013

Quotations by Alan Turing
A computer would deserve to be called intelligent if it
could deceive a human into believing that it was human.
We can only see a short distance ahead, but we can see
plenty there that needs to be done.
From his paper on the Turing test
(1943, New York: the Bell Labs Cafeteria)
His high pitched voice already stood out above the general
murmur of well-behaved junior executives grooming themselves for promotion
within the Bell corporation. Then he was suddenly heard to say: "No, I'm
not interested in developing a powerful brain. All I'm after is just a mediocre
brain, something like the President of the American Telephone and Telegraph
Company."
Quoted in A Hodges, Alan Turing the Enigma of Intelligence,
(London 1983) 251.
Science is a differential equation. Religion is a boundary
condition.
Quoted in J D Barrow, Theories of everything
...I believe that at the end of the century the use of
words and general educated opinion will have altered so much that one will be
able to speak of machines thinking without expecting to be contradicted.
Mathematical reasoning may be regarded rather schematically
as the exercise of a combination of two facilities, which we may call intuition
and ingenuity.
In the time of Galileo it was argued that the texts, 'And
the sun stood still ... and hasted not to go down about a whole day' (Joshua x.
13) and 'He laid the foundations of the earth, that it should not move at any
time' (Psalm cv. 5) were an adequate refutation of the Copernican theory.
Computing Machinery and Intelligence, Mind 59 (1950), 443.
Machines take me by surprise with great frequency.
I believe that at the end of the century the use of words
and general educated opinion will have altered so much that one will be able to
speak of machines thinking without expecting to be contradicted.

Enigma genius Alan Turing solved my childhood puzzle - a year later he
killed himself
· By Pamela Owen
Maria
Summerscale was a family friend of the tortured genius who helped crack the
German Enigma Code but who was later prosecuted for the crime of being gay
Cherished memories: Sisters Maria Summerscale and Barbara
Maher
To the world, Alan Turing is remembered as Britain’s wartime
code-breaking genius, the man who unlocked the secrets of the Enigma
machine.
But to one little girl, the tormented gay mathematician portrayed
by Benedict Cumberbatch in The Imitation Game was a beloved family friend –
who even used his brilliance to solve a childhood riddle for her.
Maria Summerscale recalled how Turing, now hailed as the
father of modern electronic computing, often watched as she struggled with the baffling
board game Solitaire.
He applied the analytical brain that helped defeat Nazi
Germany to the problem. Then, one day in 1953, he sent eight-year-old Maria a
letter.
In it was a detailed explanation, complete with a drawing,
of an infallible system for moving the pegs on a Solitaire board to ensure a win.
Less than a year after this act of kindness he killed
himself, cruelly driven over the brink by a savage law that made gay sex a criminal offence
in those days.
Maria met tragic Turing in the autumn of 1952 after her father,
psychologist Dr Franz Greenbaum, began treating him.
In March that year, Turing had been prosecuted for gross
indecency because of his relationship with Arnold Murray, a man 20 years his
junior.
In a sentence barely credible today, a judge ordered him to be
chemically castrated by a course of the hormone oestrogen, which suppressed
his libido.
Devastated Turing, who was working at Manchester University
following his Second
World War code-breaking exploits, turned to Dr Greenbaum.
Greenbaum was a Jew who fled Nazi-ruled Berlin and settled
in Manchester in 1939 with his wife Hilla and their two daughters, Barbara and
Maria.
Maria, now 69, remembered happy evenings spent with Turing
at her family home.
She told
the Sunday People: “I grew very fond of him and he was always very
friendly. He eventually became more of a family friend than a patient of my
father.
“I remember him having dinner with us often. After dinner he
would sit on the floor with me while I played Solitaire. I thought it was so
nice.
“He was a very warm person who always took an interest in
what I was doing. I grew very attached to him.”
Then came the day when Maria’s mother handed her a
registered letter.
It was from Turing. He had cracked the game – just as he
unlocked the code used in Germany’s top secret Enigma communications devices
while working at the Bletchley Park centre in Buckinghamshire.
Cracked it: Turing's letter to
Maria
Maria said: “The letter came out of the blue. He told me how
to solve the puzzle but I’ve never actually done it. I’m not good at maths and
found it too complicated. When, much later, I showed the letter to my son, he
managed it.”
Pegs on the Solitaire board must be moved around and taken off
in such a way that finally just one is left in the centre.
Turing’s method involved assigning symbols like X and O to
the pegs. He wrote: “I find it helps if I am trying to do the puzzle to use
four kinds of pieces, like this, or better still to use a board with the
squares in four colours. Each piece always stays on the same colour until it is
taken.
“You start with only four Xs and you must still have one at
the end, so you must be very careful of them. But there are 12 Os to be got rid
of. One needs to remember this all the time.”
Turing, who was about to go on holiday in Greece, added: “I
hope you all have a very nice holiday in Italian Switzerland. I shall not be
very far away at Club Mediterraneé. Yours, Alan Turing.”
Maria remembers him as a very different man to the one portrayed
in films and TV dramas.
Turing was plump, slightly unkempt, and came across to the
little girl as a shy, nervous individual.
She said: “He had quite a stammer and bit his nails. He could
be described as hyped up. But I always remember him as kind and friendly.”
Shy: But Alan Turing was
always 'kind and friendly' to Maria
Although Maria did not know it, Turing’s life was nearly over.
One of her last memories of him was when he joined a family
day trip to Blackpool.
One incident that day is chilling in light of the tragedy that
was soon to take place. Maria said: “I remember us walking along the promenade
and watching a laughing clown.
“Then Alan saw a fortune teller’s tent and decided to go in.
He came out looking very pale and nervous. He never said a word after that.
There was always this thought, ‘What was said in that tent?’”
Weeks later, Maria’s mother broke the news of Turing’s death
aged just 41.
Maria recalled: “I remember it very clearly, my mum coming
into my little room and saying, ‘I’ve got something to tell you. Alan has
died.’
“I was very upset and turned over in bed and cried. It was a
lot to experience at that age. The death of a friend. I became very attached
to him in the 18 months he visited my father, who tried to help him.
“I feel very privileged to have been a very, very tiny part of

Cracked it: An original Enigma code machine of the type used
by World War II code breaker Alan Turing
The story of how Turing and his team cracked the Enigma code,
enabling the Allies to read Nazi messages, was still top secret when he died on
June 7, 1954.
His death was recorded in The Times with a short obituary.
It said he “helped to develop a mechanical brain which he
said had solved in a few weeks a problem in higher mathematics that had been a
puzzle since the 18th Century”.
The obituary also noted how he had worked on the Ace
“automatic computing machine”.
A coroner concluded he poisoned himself with an apple laced
with cyanide, which lay partially eaten by his side.
But incredibly, the apple was never tested.
Maria, of Long Buckby, Northants, still treasures her letter
from Turing.
She added: “I’ll be going to the new movie. Benedict
Cumberbatch is a very good actor and it will be interesting to see what he does
with the role.”

Trivia
The movie went on general release in the UK on November 14th. Coventry was blitzed by the Luftwaffe on the same day in 1940. It is long rumoured that plans for the attack had been discovered by the Bletchley Park code breakers but no action was taken to stop it because the British Government were worried that such action would disclose the fact that the Enigma code had already been broken.

Early life and
career
The son of a British member of the Indian civil service,
Turing entered King’s College, University
of Cambridge, to study mathematics in 1931. After graduating in 1934,
Turing was elected to a fellowship at King’s College in recognition of his
research in probability
theory. In 1936 Turing’s seminal paper “On Computable Numbers, with an
Application to the Entscheidungsproblem [Decision
Problem]” was recommended for publication by the American
mathematician-logician Alonzo
Church, who had himself just published a paper that reached the same
conclusion as Turing’s. Later that year, Turing moved to Princeton
University to study for a Ph.D. in mathematical logic under Church’s
direction (completed in 1938).
The Entscheidungsproblem seeks an effective method
for deciding which mathematical statements are provable within a given formal
mathematical system and which are not. In 1936 Turing and Church independently
showed that in general this problem has no solution, proving that no consistent
formal
system of arithmetic is decidable. This result and others—notably the
mathematician-logician Kurt Gödel’s
incompleteness theorems—ended the dream of a system that could banish ignorance
from mathematics forever. (In fact, Turing and Church showed that even some
purely logical systems, considerably weaker than arithmetic, are undecidable.)
An important argument
of Turing’s and Church’s
was that the class of lambda-definable functions (functions on the positive
integers whose values can be calculated by a process of repeated substitution)
coincides with the class of all functions that are effectively calculable—or computable.
This claim is now known as Church’s thesis—or as the Church-Turing thesis when
stated in the form that any effectively calculable function
can be calculated by a universal Turing
machine, a type of abstract computer
that Turing had introduced in the course of his proof. (Turing showed in 1936
that the two formulations of the thesis are equivalent by proving that the
lambda-definable functions and the functions that can be calculated by a
universal Turing
machine are identical.) In a review of Turing’s work, Church acknowledged
the superiority of Turing’s formulation of the thesis over his own, saying that
the concept of computability
by a Turing machine “has the advantage of making the identification with
effectiveness…evident immediately.”
Code
breaker
In the summer of 1938 Turing returned from the United States
to his fellowship at King’s College. At the outbreak of hostilities with
Germany in September 1939, he joined the wartime headquarters of the Government
Code and Cypher School at Bletchley Park, Buckinghamshire. The British
government had just been given the details of efforts by the Poles, assisted by
the French, to break the Enigma code,
used by the German military for their radio communications. As early as 1932, a
small team of Polish mathematician-cryptanalysts, led by Marian Rejewski, had
succeeded in reconstructing the internal wiring of the type of Enigma
machine used by the Germans, and by 1938 they had devised a code-breaking
machine, code-named Bomba
(the Polish word for a type of ice cream). The Bomba depended for its
success on German operating procedures, and a change in procedures in May 1940
rendered the Bomba virtually useless. During 1939 and the spring of
1940, Turing and others designed a radically different code-breaking machine
known as the Bombe.
Turing’s ingenious Bombes kept the Allies supplied with intelligence for the
remainder of the war. By early 1942 the Bletchley Park cryptanalysts were
decoding about 39,000 intercepted messages each month, which rose subsequently
to more than 84,000 per month. At the end of the war, Turing was made an
officer of the Order of the British Empire for his code-breaking work.
Computer
designer
In 1945, the war being over, Turing was recruited to the
National Physical Laboratory (NPL) in London to design and develop an
electronic computer.
His design for the Automatic
Computing Engine (ACE) was the first relatively complete specification of
an electronic stored-program general-purpose digital
computer. Had Turing’s ACE been built as planned, it would have had
considerably more memory than any of the other early computers, as well as
being faster. However, his colleagues at NPL thought the engineering too
difficult to attempt, and a much simpler machine was built, the Pilot Model
ACE.
In the end, NPL lost the race to build the world’s first
working electronic stored-program digital computer—an honour that went to the
Royal Society Computing Machine Laboratory at the University
of Manchester in June 1948. Discouraged by the delays at NPL, Turing took
up the deputy directorship of the Computing Machine Laboratory in that year
(there was no director). His earlier theoretical concept of a universal Turing
machine had been a fundamental influence on the Manchester
computer project from its inception. Turing’s principal practical contribution
after his arrival at Manchester was to design the programming system of the
Ferranti Mark I, the world’s first commercially available electronic digital
computer.
Artificial
intelligence pioneer
Turing was a founding father of modern
cognitive science
and a leading early exponent of the hypothesis that the human brain is in large
part a digital computing machine. He theorized that the cortex at birth is an
“unorganised machine” that through “training” becomes organized “into a
universal machine or something like it.” A pioneer of artificial
intelligence, Turing proposed (1950) what subsequently became known as the Turing test
as a criterion for whether a machine thinks.

Alan Turing was born at Paddington, London. His father, Julius Mathison Turing,
was a British member of the Indian Civil Service and he was often abroad.
Alan's mother, Ethel Sara Stoney, was the daughter of the chief engineer of the
Madras railways and Alan's parents had met and married in India. When Alan was
about one year old his mother rejoined her husband in India, leaving Alan in
England with friends of the family. Alan was sent to school but did not seem to
be obtaining any benefit so he was removed from the school after a few months.
Next he was sent to Hazlehurst
Preparatory School where he seemed to be an 'average to good' pupil in most
subjects but was greatly taken up with following his own ideas. He became
interested in chess while at this school and he also joined the debating
society. He completed his Common Entrance Examination in 1926 and then went to
Sherborne School. Now 1926 was the year of the general strike and when the
strike was in progress Turing cycled 60 miles to the school from his home, not
too demanding a task for Turing who later was to become a fine athlete of
almost Olympic standard. He found it very difficult to fit into what was
expected at this public school, yet his mother had been so determined that he
should have a public school education. Many of the most original thinkers have
found conventional schooling an almost incomprehensible process and this seems
to have been the case for Turing. His genius drove him in his own directions
rather than those required by his teachers.
He was criticised for his handwriting,
struggled at English, and even in mathematics he was too interested with his
own ideas to produce solutions to problems using the methods taught by his
teachers. Despite producing unconventional answers, Turing did win almost every
possible mathematics prize while at Sherborne. In chemistry, a subject which
had interested him from a very early age, he carried out experiments following
his own agenda which did not please his teacher. Turing's headmaster wrote (see
for example [6]):-
If he is to stay at Public School, he
must aim at becoming educated. If he is to be solely a Scientific Specialist,
he is wasting his time at a Public School.
This says far more about the school
system that Turing was being subjected to than it does about Turing himself.
However, Turing learnt deep mathematics while at school, although his teachers
were probably not aware of the studies he was making on his own. He read Einstein's
papers on relativity and he also read about quantum mechanics in Eddington's
The nature of the physical world.
An event which was to greatly affect
Turing throughout his life took place in 1928. He formed a close friendship
with Christopher Morcom, a pupil in the year above him at school, and the two
worked together on scientific ideas. Perhaps for the first time Turing was able
to find someone with whom he could share his thoughts and ideas. However Morcom
died in February 1930 and the experience was a shattering one to Turing. He had
a premonition of Morcom's death at the very instant that he was taken ill and
felt that this was something beyond what science could explain. He wrote later
(see for example [6]):-
It is not difficult to explain these
things away - but, I wonder!
Despite the difficult school years,
Turing entered King's College, Cambridge, in 1931 to study mathematics. This
was not achieved without difficulty. Turing sat the scholarship examinations in
1929 and won an exhibition, but not a scholarship. Not satisfied with this
performance, he took the examinations again in the following year, this time
winning a scholarship. In many ways Cambridge was a much easier place for
unconventional people like Turing than school had been. He was now much more
able to explore his own ideas and he read Russell's
Introduction to mathematical philosophy in 1933. At about the same time
he read von
Neumann's 1932 text on quantum mechanics, a subject he returned to a number
of times throughout his life.
The year 1933 saw the beginnings of
Turing's interest in mathematical logic. He read a paper to the Moral Science
Club at Cambridge in December of that year of which the following minute was
recorded (see for example [6]):-
A M Turing read a paper on
"Mathematics and logic". He suggested that a purely logistic view of
mathematics was inadequate; and that mathematical propositions possessed a
variety of interpretations of which the logistic was merely one.
Of course 1933 was also the year of
Hitler's rise in Germany and of an anti-war movement in Britain. Turing joined
the anti-war movement but he did not drift towards Marxism, nor pacifism, as
happened to many.
Turing graduated in 1934 then, in the
spring of 1935, he attended Max
Newman's advanced course on the foundations of mathematics. This course
studied Gödel's
incompleteness results and Hilbert's
question on decidability. In one sense 'decidability' was a simple question,
namely given a mathematical proposition could one find an algorithm which would
decide if the proposition was true of false. For many propositions it was easy
to find such an algorithm. The real difficulty arose in proving that for
certain propositions no such algorithm existed. When given an algorithm to
solve a problem it was clear that it was indeed an algorithm, yet there was no
definition of an algorithm which was rigorous enough to allow one to prove that
none existed. Turing began to work on these ideas.
Turing was elected a fellow of King's
College, Cambridge, in 1935 for a dissertation On the Gaussian error
function which proved fundamental results on probability theory, namely the central limit
theorem. Although the central limit theorem had recently been discovered,
Turing was not aware of this and discovered it independently. In 1936 Turing
was a Smith's Prizeman.
Turing's achievements at Cambridge had
been on account of his work in probability theory. However, he had been working
on the decidability questions since attending Newman's
course. In 1936 he published On Computable Numbers, with an application to
the Entscheidungsproblem. It is in this paper that Turing introduced an
abstract machine, now called a "Turing machine", which moved from one
state to another using a precise finite set of rules (given by a finite table)
and depending on a single symbol it read from a tape.
The Turing machine could write a symbol
on the tape, or delete a symbol from the tape. Turing wrote [13]:-
Some of the symbols written down will
form the sequences of figures which is the decimal of the real number which is
being computed. The others are just rough notes to "assist the
memory". It will only be these rough notes which will be liable to
erasure.
He defined a computable number as real number whose decimal
expansion could be produced by a Turing machine starting with a blank tape. He
showed that π was computable, but since only countably many real numbers are computable, most real numbers are not computable. He then
described a number which is not computable and remarks that this seems to be a
paradox since he appears to have described in finite terms, a number which
cannot be described in finite terms. However, Turing understood the source of
the apparent paradox. It is impossible to decide (using another Turing machine)
whether a Turing machine with a given table of instructions will output an
infinite sequence of numbers.
Although this paper contains ideas which
have proved of fundamental importance to mathematics and to computer science
ever since it appeared, publishing it in the Proceedings of the London
Mathematical Society did not prove easy. The reason was that Alonzo
Church published An unsolvable problem in elementary number theory in the American Journal of
Mathematics in 1936 which also proves that there is no decision procedure
for arithmetic. Turing's approach is very different from that of Church
but Newman
had to argue the case for publication of Turing's paper before the London Mathematical Society would publish it.
Turing's revised paper contains a reference to Church's
results and the paper, first completed in April 1936, was revised in this way
in August 1936 and it appeared in print in 1937.
A good feature of the resulting
discussions with Church
was that Turing became a graduate student at Princeton University in 1936. At
Princeton, Turing undertook research under Church's
supervision and he returned to England in 1938, having been back in England for
the summer vacation in 1937 when he first met Wittgenstein.
The major publication which came out of his work at Princeton was Systems of
Logic Based on Ordinals which was published in 1939. Newman
writes in [13]:-
This paper is full of interesting
suggestions and ideas. ... [It]
throws much light on Turing's views on the place of intuition in mathematical
proof.
Before this paper appeared, Turing
published two other papers on rather more conventional mathematical topics. One
of these papers discussed methods of approximating Lie groups by finite groups.
The other paper proves results on extensions of groups, which were first proved
by Reinhold Baer,
giving a simpler and more unified approach.
Perhaps the most remarkable feature of
Turing's work on Turing machines was that he was describing a modern computer
before technology had reached the point where construction was a realistic
proposition. He had proved in his 1936 paper that a universal Turing machine
existed [13]:-
... which can be made to do the work of
any special-purpose machine, that is to say to carry out any piece of
computing, if a tape bearing suitable "instructions" is inserted into
it.
Although to Turing a "computer"
was a person who carried out a computation, we must see in his description of a
universal Turing machine what we today think of as a computer with the tape as
the program.
While at Princeton Turing had played with
the idea of constructing a computer. Once back at Cambridge in 1938 he starting
to build an analogue mechanical device to investigate the Riemann hypothesis, which many consider today
the biggest unsolved problem in mathematics. However, his work would soon take
on a new aspect for he was contacted, soon after his return, by the Government
Code and Cypher School who asked him to help them in their work on breaking the
German Enigma codes.
When war was declared in 1939 Turing
immediately moved to work full-time at the Government Code and Cypher School at
Bletchley Park. Although the work carried out at Bletchley Park was covered by
the Official Secrets Act, much has recently become public knowledge. Turing's
brilliant ideas in solving codes, and developing computers to assist break
them, may have saved more lives of military personnel in the course of the war
than any other. It was also a happy time for him [13]:-
... perhaps the happiest of his life,
with full scope for his inventiveness, a mild routine to shape the day, and a
congenial set of fellow-workers.
Together with another mathematician W G
Welchman, Turing developed the Bombe, a machine based on earlier work by
Polish mathematicians, which from late 1940 was decoding all messages sent by
the Enigma machines of the Luftwaffe. The Enigma machines of the German navy
were much harder to break but this was the type of challenge which Turing
enjoyed. By the middle of 1941 Turing's statistical approach, together with
captured information, had led to the German navy signals being decoded at
Bletchley.
From November 1942 until March 1943
Turing was in the United States liaising over decoding issues and also on a
speech secrecy system. Changes in the way the Germans encoded their messages
had meant that Bletchley lost the ability to decode the messages. Turing was
not directly involved with the successful breaking of these more complex codes,
but his ideas proved of the greatest importance in this work. Turing was
awarded the O.B.E. in 1945 for his vital contribution to the war effort.
At the end of the war Turing was invited
by the National Physical Laboratory in London to design a computer. His report
proposing the Automatic Computing Engine (ACE) was submitted in March 1946.
Turing's design was at that point an original detailed design and prospectus
for a computer in the modern sense. The size of storage he planned for the ACE
was regarded by most who considered the report as hopelessly over-ambitious and
there were delays in the project being approved.
Turing returned to Cambridge for the
academic year 1947-48 where his interests ranged over many topics far removed
from computers or mathematics; in particular he studied neurology and
physiology. He did not forget about computers during this period, however, and
he wrote code for programming computers. He had interests outside the academic
world too, having taken up athletics seriously after the end of the war. He was
a member of Walton Athletic Club winning their 3 mile and 10 mile championship
in record time. He ran in the A.A.A. Marathon in 1947 and was placed fifth.
By 1948 Newman
was the professor of mathematics at the University of Manchester and he offered
Turing a readership there. Turing resigned from the National Physical
Laboratory to take up the post in Manchester. Newman writes in [13]
that in Manchester:-
... work was beginning on the
construction of a computing machine by F C Williams and T Kilburn. The
expectation was that Turing would lead the mathematical side of the work, and
for a few years he continued to work, first on the design of the subroutines
out of which the larger programs for such a machine are built, and then, as
this kind of work became standardised, on more general problems of numerical
analysis.
In 1950 Turing published Computing
machinery and intelligence in Mind. It is another remarkable work
from his brilliantly inventive mind which seemed to foresee the questions which
would arise as computers developed. He studied problems which today lie at the
heart of artificial intelligence. It was in this 1950 paper that he proposed
the Turing Test which is still today the test people apply in attempting to
answer whether a computer can be intelligent [1]:-
... he became involved in discussions on
the contrasts and similarities between machines and brains. Turing's view,
expressed with great force and wit, was that it was for those who saw an
unbridgeable gap between the two to say just where the difference lay.
Turing did not forget about questions of
decidability which had been the starting point for his brilliant mathematical
publications. One of the main problems in the theory of group presentations was the question: given any
word in a finitely presented groups is there an algorithm to decide if the word
is equal to the identity. Post
had proved that for semigroups no such algorithm exist. Turing
thought at first that he had proved the same result for groups but, just before
giving a seminar on his proof, he discovered an error. He was able to rescue
from his faulty proof the fact that there was a cancellative semigroup with
insoluble word problem and he published this result in 1950. Boone
used the ideas from this paper by Turing to prove the existence of a group with
insoluble word problem in 1957.
Turing was elected a Fellow of the Royal Society of London in 1951, mainly for his
work on Turing machines in 1936. By 1951 he was working on the application of
mathematical theory to biological forms. In 1952 he published the first part of
his theoretical study of morphogenesis, the development of pattern and form in
living organisms.
Turing was arrested for violation of
British homosexuality statutes in 1952 when he reported to the police details
of a homosexual affair. He had gone to the police because he had been
threatened with blackmail. He was tried as a homosexual on 31 March 1952,
offering no defence other than that he saw nothing wrong in his actions. Found
guilty he was given the alternatives of prison or oestrogen injections for a
year. He accepted the latter and returned to a wide range of academic pursuits.
Not only did he press forward with
further study of morphogenesis, but he also worked on new ideas in quantum
theory, on the representation of elementary particles by spinors, and on
relativity theory. Although he was completely open about his sexuality, he had
a further unhappiness which he was forbidden to talk about due to the Official
Secrets Act.
The decoding operation at Bletchley Park
became the basis for the new decoding and intelligence work at GCHQ. With the
cold war this became an important operation and Turing continued to work for
GCHQ, although his Manchester colleagues were totally unaware of this. After
his conviction, his security clearance was withdrawn. Worse than that, security
officers were now extremely worried that someone with complete knowledge of the
work going on at GCHQ was now labelled a security risk. He had many foreign
colleagues, as any academic would, but the police began to investigate his
foreign visitors. A holiday which Turing took in Greece in 1953 caused consternation
among the security officers.
Turing died of potassium cyanide
poisoning while conducting electrolysis experiments. The cyanide was found on a
half eaten apple beside him. An inquest concluded that it was self-administered
but his mother always maintained that it was an accident.

Turing as a runner
Alan Turing ran a little while he was at Sherbourne school, usually when football was cancelled because of bad weather. He did not run while an undergraduate at Cambridge, preferring to row, but once he had won his fellowship to King's College he began to run more seriously, his frequent route being from Cambridge to Ely and back, a distance of around 50 km. He did a little running while at Bletchley but only when he moved to the National Physical Laboratory did he take up running more seriously. J F Harding was the secretary of Walton Athletic Club at this time and he recalls first meeting Turing out on a run:-
We heard him rather than saw him. He made a terrible grunting noise when he was running, but before we could say anything to him, he was past us like a shot out of a gun. A couple of nights later, we kept up with him long enough for me to ask him who he ran for. When he said nobody, we invited him to join Walton. He did and immediately became our best runner. Looking back, he was the typical absent-minded professor. He looked different to the rest of the lads; he was rather untidily dressed, good quality clothes mind, but no creases in them; he used a tie to hold his trousers up; if he wore a necktie, it was never knotted properly; and he had hair that just stuck up at the back. He was very popular with the boys, but he wasn't one of them. He was a strange character, a very reserved sort, but he mixed in with everyone quite well: he was even a member of our committee.Turing came fifth in the AAA marathon which was used as a qualifying event for the 1949 Olympic games. His time was 2 hours 46.03 minutes which by modern marathon times does not look so great but was good at that time. To put it in perspective, the winning Olympic time was only 10 minutes better at the 1948 Olympics. A leg injury put an end to further serious running by Turing. However, even after he moved to Manchester he still occasionally represented Walton in events. The last event he ran for the club was in April 1950 when he was on the Walton relay team in the London to Brighton race. Also a member of the same Walton team was Chris Chataway, who a few years later went on to help Roger Bannister break the four minute mile. P Butcher
We had no idea what he did, and what a great man he was. We didn't realise it until all the Enigma business came out. We didn't even know where he worked until he asked us if Walton would have a match with the NPL. It was the first time I'd been in the grounds. Another time, we went on our first ever foreign trip to Nijmegen in Holland he couldn't come, but he gave me five pounds, which was a lot of money in those days, and said "Buy the boys a drink for me". I asked him one day why he punished himself so much in training. He told me "I have such a stressful job that the only way I can get it out of my mind is by running hard; its the only way I can get some release."

Joan Clarke's parents were William Kemp Lowther Clarke, a Clergyman, and Dorothy
Elisabeth Clarke. She was their youngest child and had three elder brothers and
one sister. Joan was educated at Dulwich High School and in 1936 matriculated
at Newnham College, Cambridge, to study Mathematics. In 1937 and 1939
respectively, she achieved a First in Part I and Part II of the Mathematical
Tripos (a three-year course leading to a BA degree) and became a Wrangler. In
1939 Clarke graduated, achieving a double first in Mathematics; however this
was merely the title of her degree, as Cambridge did not admit women to
"full membership of the body academic" until after the end of the
Second World War. In 1939 Clarke was awarded the distinguished Philippa
Fawcett Prize and in 1939-1940 the Helen Gladstone Scholarship.
Gordon Welchman was one of the four top
mathematicians recruited in 1939 to set up decoding operations at Bletchley
Park. During the time that Joan Clarke was an undergraduate at Cambridge,
Gordon Welchman had supervised her in Geometry during Part II and, aware of her
mathematical ability, he was responsible for recruiting Clarke to join the 'Government
Code and Cypher School' (GCCS) at Bletchley Park. Records describe Clarke as
congenial but shy, gentle and kind, non-aggressive and always subordinate to
the men in her life; qualities that would allow her to conform within the male
dominated world of Bletchley Park. Let us examine in a little more detail the
background to the GCCS.
The Germans had successfully developed a
device called an Enigma machine to encrypt their messages. They believed that
the Enigma code was unbreakable. The machine was an electro-mechanical device
that relied on assorted rotating wheels and rotors to scramble plain text
messages into jumbled cyphertext. The machine's variable elements could be set
in billions of combinations. The Germans changed the settings on the Enigma
machines every day and each branch of their military intelligence and civil
services used different enigma settings. Not knowing the settings meant the
chances of being able to decipher a message was an astonishing 150 million
million million to one.
To defeat the Germans, it was imperative
that the Enigma code was broken and Churchill's Government searched the country
for the best mathematicians, chess champions, Egyptologists and others of
suitable ability, who would know anything about the possible permutations of
formal systems, to assist in the operation of cracking the enigma code. In
August 1939, the GCCS was set up in great secrecy at Bletchley Park, a
Victorian mansion in Buckinghamshire, with the singular intention of breaking
the German Enigma code. Bletchley Park would provide a safer home than London
for the code breakers, plus it had rail and teleprinter connections to all
parts of the country and was at the junction of a major road - all ideal
attributes.
To highlight the complexity of the task
the code breakers faced, Alastair Denniston, who was to become the first Head
of Bletchley Park, at one time actually shared the German belief that the
military Enigma was invincible; he is recorded as telling his fellow code
breakers [6]:-
... all German codes were unbreakable.
Joan Clarke and her colleagues were
destined to prove him wrong. Initially, Clarke was not exactly told what the
job would entail, only that [1]:-
... the work didn't really need
mathematics but mathematicians tended to be good at it.
Clarke accepted the post and the
challenge, agreeing to start work at Bletchley Park in June 1940, after she had
completed Part III of the Mathematical Tripos. She arrived at Bletchley Park on
17 June 1940. Her first placement was humble enough, joining a large group of
women, generally referred to as "the girls" who were engaged in
routine clerical work in Hut 8. Even though the ratio of women to men working
at Bletchley Park was 8:1, women were mostly employed in clerical and
administration work and not the more intricate cryptology, which was a male
dominated area. During her time at Bletchley Park, Clarke only ever knew of one
other female mathematical cryptanalyst. Clarke was originally paid £2 a week -
but as this was an era of female discrimination in the workplace, similarly
qualified men received significantly more money.
Clarke's first promotion at work was to
Linguist Grade - even though Clarke did not speak another language - this
promotion was engineered to enable her to earn extra money - thereby
acknowledging her workload and contributions to the team. Clarke has written
that she [1]:-
... enjoyed answering a questionnaire
with 'Grade: Linguist, Languages: none!
She believed she struggled to get a
further promotion purely because of her sex. The Deputy Director at Bletchley
Park, Commander Edward Travis, later told her that she might have to enroll in
the WRNS (Women's Royal Naval Service) in order to earn significantly more
money, but Clarke did not wish to pursue this route.
In Hut 8, Clarke was quickly promoted to
her own table in a small room, joining a team which included Alan
Turing, Tony Kendrick and Peter Twinn. Collectively they were applying
themselves to non-routine tasks of trying to break the complex Naval Enigma -
codenamed Dolphin.
William F Friedman, the founder of modern
US cryptology wrote that a code breaker required unusual powers of inductive
and deductive reasoning, much concentration, perseverance and a vivid
imagination. The fact that Joan Clarke was able to move so quickly into the
male cryptology area at Bletchley Park indicates she possessed these
attributes.
The Naval Enigma was different to the
Army and Luftwaffe Enigma and more complex to break. Firstly, two extra wheels
had been added so there was now a choice of three from five giving a total
number of 336 possible wheel orders. Secondly, to give added security, a
different indicator system was applied; instead of transmitting the indicators
directly, they were super enciphered using bigram tables.
The need for breaking the Naval Enigma
code was growing greater by the day. By mid 1940, following the German
occupation of France, German U-Boats now had easy access to the Atlantic from
the Bay of Biscay. Britain had become extremely dependent on imports and was
importing half of its food and all of its oil. The provisions now had to come
across the Atlantic from North America and the convoys rapidly become targets
for the U-boats. At one stage, Britain was only three days from running out of
food and therefore it was crucial the Naval Enigma code was broken.
In early May 1940, matched plaintext and
Enigma cyphertext became available from a German patrol boat, Schiff 26,
captured off the Norwegian Coast. Joan Clarke's first task on arriving at
Bletchley Park was to use a new key-finding aid called the Bombe, against the
recovered data. This successfully resulted in Clarke and her colleagues
breaking approximately six days of April traffic over a period of three months.
By the end of 1940 rotors VI, VII and
VIII had been recovered and a library of cribs built up - the cribs were
assembled by using anticipated text from German weather ships that were
relaying messages in the German Meteorological cipher (which was easier to
decipher than the dolphin cipher). This provided Clarke and the team, with the
knowledge of what information to expect in a message and how the Naval
indicator system worked.
With 336 possible rotor combinations and
the double indicator decipherment, the usual methods of codebreaking were
futile. For this reason Alan
Turing invented a new codebreaking technique called Banburismus. The name
was given to the technique because it involved the use of long sheets of paper
printed in Banbury. The aim of this method was to identify the right hand and
middle wheel and thus reduce the possible wheel orders from 336 to as little as
20. There were few Bombes in 1941 and with so many different combinations of
wheels it was far too time consuming. Turing's
method exploited the German cryptographic mistake of having different positions
of turnover for each wheel (though the Germans did learn from their mistake and
wheels VI, VII and VIII all had the same positions of turnover). Professor Jack
Good, who also worked on Banburismus, has since said that it was the first
example of Sequential Analysis and describes it as [6]:-
... a complicated but enjoyable game.
There were eight male Banburists and Joan
Clarke was the only female Banburist. However, she was one of the best
Banburists and was so enthusiastic and fascinated with the technique that she
would sometimes be unwilling to hand over her workings at the end of her shift
and would continue to see if a few more tests would produce a result. A method
known as Yoxallismus was devised to speed up this work and was named after its
inventor Leslie Yoxall. Shortly afterwards, Clarke devised a method of her own
to also speed up the technique, and she was told, to her surprise, that she had
used pure Dillysimus. This was a method which had been invented by Dillwin
(Dilly) Knox, one of the few cryptographic experts of World War One, who had
originally headed the attack on the German enigma.
Banburismus was impossible without the Bigram substitution tables and therefore without them, very little progress against the Naval Enigma was accomplished. The breakthrough came in February and June 1941, when trawlers were captured along with cipher equipment and codes. Clarke and her co-workers successfully performed Banburismus for two years, only stopping in August 1943 when ultra fast Bombes became available. The successful results of their efforts were evident immediately. Between March and June 1941, the Wolf Packs (a term used to describe the mass attack tactics used against convoys by U-boats), had sunk 282,000 tons of shipping a month. From July, the figure dropped to 120,000 tons a month and by November, to 62,000 tons.

From July, the figure dropped to 120,000 tons a month and by November, to 62,000 tons.
In the spring of 1941, Joan Clarke
developed a close friendship with her Hut 8 colleague Alan
Turing. Clarke and Turing
had actually met previously to working at Bletchley Park, as Turing
was a friend of her older brother. For a time, they became inseparable, Turing
arranged their shifts so they could work together and they spent many of their
leave days together. Soon after this blossoming friendship, Turing
proposed marriage and Clarke accepted. However, devastatingly for Clarke, a few
days after the proposal, Turing
told her [2]:-
... to not count on it working out as he
had homosexual tendencies.
Turing
expected this to be the end of their affair, but Clarke was undeterred by his
declaration, and their engagement continued. To understand her decision to
continue with the engagement following his disclosure, it has to be made clear
that during this period in history, marriage for many women, was considered a
social duty and it was not necessary that marriage should correspond with
sexual desires.
Clarke was formally introduced to Alan
Turing's family and vice versa, he gave her an engagement ring, although
she did not wear it when in the Hut, choosing to keep their engagement secret
from their colleagues. They talked of the future and Turing
told her of his desire to have children. They shared many interests, both were
keen chess players and, as Clarke had studied Botany at school, she could
become involved with Turing's
life long enthusiasm of the growth and form of plant life. When Turing
wrote his account of the Enigma Theory for the use of new recruits in Hut 6 and
Hut 8, (known at Bletchley Park as "Prof's book") he used Joan Clarke
as his 'guinea pig' - she had to read and trial it, checking that it was
understandable for them.
In the late summer of 1941, following a
holiday in North Wales, their engagement ended by mutual consent, because of Turing's
belief that the marriage would be a failure because of his homosexuality.
Clarke was to remain friends with Turing
for the rest of his life. Years later, after they had both left Bletchley Park,
Turing
revealed in a letter to Clarke that he "did occasionally practice"
his homosexuality and that he had been "found out". Homosexuality was
illegal at this time, with imprisonment or chemical castration the punishment
for offenders. In 1952 in Manchester, Alan
Turing was convicted of "acts of gross indecency" following
admission to a relationship with another man. In his defence, Turing
said he did not consider he had done anything wrong. As a result of the
conviction, Turing
was given oestrogen injections for a year, and shortly afterwards Alan
Turing committed suicide.
As well as continuing to break the
Dolphin Enigma, Clarke and the Naval Enigma team were allotted responsibility
for breaking the Shark Enigma - codename for the 4-rotor key introduced in late
1941. The Hut 8 team successfully broke the code in mid-December 1942, but at
the end of 1943, the US codebreaking unit (OP-20-G) took over the
responsibility for continuing with the Shark Enigma. As a result, many of the
Hut 8 staff transferred to other parts of Bletchley Park. However, Joan Clarke
remained in Hut 8, becoming Deputy Head in early 1944. She and her team
continued to break the Naval Enigma until the end of the war. The war in the
west officially ended at midnight on 9 May 1945. By March 1946, all the workers
had vacated Bletchley Park and every scrap of evidence of their secret code
breaking exploits was disposed of.
In 1947, Clarke was appointed a Member of
the British Empire (MBE) for her codebreaking expertise during the war, but due
to the restraints of the Official Secrets Act, her work was to remain
confidential for many years to come. The codebreaking effort continued when the
GCCS was renamed GCHQ (Government Communications Headquarters) and moved to
Eastcote. Clarke transferred to Bletchley Park's successor and there she met a
colleague named Lieutenant-Colonel J (Jock) K R Murray, a retired army officer,
whom she went on to marry in 1952. The couple did not have children.
Shortly after their marriage and due to
her husband's poor health, the couple moved to Scotland where they both had a
keen interest in Scottish History. It was from her husband that Clarke gained
an interest in numismatic history, as he had published many important papers on
the Scottish coinage of the 16th and 17th centuries. They
returned to Cheltenham in 1962 and Clarke rejoined the GCHQ where she remained
until retiring at the age of 60 in 1977. In 1974, after the lifting of Official
Secrets Act restrictions, details of the code breakers brilliant work became
widely known. The Bombe and the impact of all their endeavors began to emerge.
In 1986, following the death of her
husband, Clarke moved to Headington, near Oxford, where she continued her
numismatic research. The "Numismatic Circular" recorded [6]:-
Joan Murray's greatest achievement was to
establish the sequence of gold unicorns and heavy groats of James III and James
IV, an extremely complex series which caused great difficulty for previous
students.
In 1987, Clarke was awarded the Sandford
Saltus Medal - the Society's premier distinction, voted for by its members for
scholarly contributions to British Numismatics.
After her retirement, Clarke also
assisted Sir Harry Hinsley on what became Appendix 30 to Volume 3, Issue 2 of
the 1988 British Intelligence in the Second World War, a substantially revised
assessment of the Polish, French and British contributions to breaking the
Enigma. In 1987, the play "Breaking the Code" by Hugh Whitmore, about
the life of Alan
Turing, opened in London. The play is based on the 1983 book, "Alan
Turing, the Enigma" by Andrew Hodges. Whitmore based the character in the
play named Pat Smith, on Joan Clarke. Clarke co-operated with Andrew Hodges
when he was researching and writing his book, but she chose not see Whitmore's
play, declaring that [7:-
... it would have been too painful.
Joan Clarke died at her home in
Headington, Oxford. Her obituary offers an insight into how she was perceived,
both personally and professionally [7]:-
She is remembered as "one of the
really good cryptanalysts" of GCHQ who was liked and admired by colleagues
throughout her long and dedicated career.
The full extent of Joan Clarke's
mathematical contributions and accomplishments at Bletchley Park remain
unknown, because of the continuing secrecy amongst cryptanalysts. Furthermore,
Clarke's work is still somewhat overshadowed by her relationship with Alan
Turing. Joan Clarke played a notable role in Britain's crucial achievements
during World War II and it is clear that her mathematical expertise on the
Naval Enigma helped to shorten the war and thereby save thousands of lives.

Unseen worlds: Defiant until Death ----- ----------------------- In ‘The Imitation Game,’ a portrait of what bias cost EnglandGay rights movies frequently work as both art and politics by presenting viewers with sympathetic gay and lesbian characters, and then, once we feel attached to these fictional people, tallying up the ways that prejudice injures them personally. But “The Imitation Game,” a handsome new movie about Alan Turing, inventor of modern computing, and the work he did for the British at Bletchley Park to break the German Engima code during World War II, dares to suggest something grander: that the equal participation of gay people and women in public life is a matter of national self-interest. “The Imitation Game” takes as its center the close friendship between Turing (Benedict Cumberbatch, in a typically sensitive performance) and Joan Clarke (Keira Knightley), Turing’s colleague, confidante and for a brief time, his fianceé. Screenwriter Graham Moore says he was animated by “The way Alan Turing and Joan Clarke were these two people who were each kind of cast out of traditional authority roles in traditional society in certain ways: her, because she was a woman, he because he was a gay man at a time when that was literally illegal, not simply frowned upon. And how these two outsiders were able to find each other and see the world in a way that no one else had, and to accomplish these things that no one thought were possible.” (Disclosure: Moore and I met at a group dinner in 2013 and have seen each other socially in similar setting two other times since.) At Bletchley Park, people like Turing and Clark were given opportunities to make full use of their talents on behalf of their country in a way that would not have been possible for them in peacetime. There were slights, of course. Clark had to be commissioned onto the Enigma process as a linguist, rather than as a full code-breaker because of her gender. “That was the only way they could get her the security clearance and get her into the rooms,” Moore explains. Other women were hired as clerks, director Morten Tyldum notes. And some secrets were more dangerous than others. Part of “The Imitation Game” is taken up in a tense minuet between Turing and John Cairncross, the Bletchley codebreaker turned Soviet spy played by “Downton Abbey” star Allen Leech. As each man’s discovers the other’s secret–Turing’s homosexuality and Cairncross’ treachery–the balance of power shifts dangerously between them. The unnecessary suspicion of Turing’s homosexuality meant that he was not free to report a real security risk without having his own secret exposed, something that surely would have resulted in his removal from the project. Leech says he was fascinated by “the power that you can have when you have all the information, but also the moral element of what you do with that information. And you have that information when they break the code, how they’re actually going to filter that through into the war effort.” Some of those same dynamics played out in the post-war years. While in the post-War United States, women who had worked in factories were encouraged to embrace a return to domestic life to free up their jobs for men who were returning from Europe and the Pacific, women and gay men who worked at Bletchley faced a different dilemma. The code of secrecy that had guided their intelligence work bound them long after they ended their war-time service. Leech says he heard a story of a couple who only learned they had both worked at Bletchley decades into their marriage, while Moore recalls a meeting with a woman who wasn’t even aware until recently that she had helped break Enigma. The consequences of this code of silence were more than personal. In order for women and gay men who served at Bletchley to use their service there as an argument that they ought to have equal opportunities and equal rights, they would have to have to breach the secrecy that governed their conduct there. The very act of speaking up on their own behalf would render them untrustworthy, a contradiction also captured by the excellent television drama “The Bletchley Circle.” During the war, this delicate balance might have been sustainable. In a sense, Moore suggests, Britain’s own climate of sexual repression created a man who was perfectly suited to the Enigma project, which required the Allies not only to break Germany’s highest-level codes, but then not to act on that information in a way that might indicate to the Germans that their communications were no longer secure. Just as Turing could not act on his self-knowledge, the Allies had to continue to let the Axis kill huge numbers of soldiers and civilians so they could continue to make any use of the Enigma-encrypted messages at all. “You’ve got this man who’s not qualified to sort of be this high-level spy in any way, but that he’s been keeping secrets every single day of his life,” Moore reflects. “He’s been imitating someone else every day and now he has to help the whole military apparatus imitate, in some way, something it’s not.” But Enigma need not have been the end of Turing’s contributions to Britain and to the world. Moore says he was moved by “The idea of institutionally, what we lost due to the systemic persecution of gay men in the middle part of the century, to think of what Alan Turing could have accomplished if he hadn’t died so young.” The idea that Alan Turing’s sexuality was so dangerous that he had to be chemically castrated didn’t just result in his eventual suicide. It was a tragedy for England. Gay rights, “The Imitation Game” suggests, aren’t just a matter of sympathy for others. Sixty years after Alan Turing’s suicide, it’s finally time to recognize full equality as a matter of our collective self-interest. http://www.washingtonpost.com/news/act-four/wp/2014/12/08/in-the-imitation-game-a-portrait-of-what-bias-cost-england/ |
