Turing in 1951

A portrait of

Alan Mathison Turing, F.R.S., O.B.E.

in 1951

This Page is the gateway and guide
to this large Website
dedicated to Alan Turing (1912-1954).

Behind it lie 23 further pages for you to explore.


Who was Alan Turing?

Founder of computer science, mathematician, philosopher,
codebreaker, strange visionary and a gay man before his time:

1928: Studies relativity
1930: Death of friend Christopher Morcom
1931-34: Undergraduate at King's College, Cambridge University

1935: Elected fellow of King's College, Cambridge
1936: The Turing machine: On Computable Numbers... submitted
1936-38: At Princeton University. Ph.D. Papers in logic, algebra, number theory
1938-39: Return to Cambridge. Introduced to German Enigma cipher problem
1939-40 Devises the Bombe, machine for Enigma decryption
1939-42: Breaking of U-boat Enigma cipher, saving battle of the Atlantic

1949: Work on programming and world's first serious use of a computer
1950: Philosophical paper on machine intelligence: the Turing Test
1951: Elected FRS. Paper on non-linear morphogenesis theory
1952: Arrested and tried as a homosexual, loss of security clearance
1953-54: Unfinished work in biology and physics
1954 (7 June): Death by cyanide poisoning, Wilmslow, Cheshire.


To find out more: read a short biography.

It is an extended version of the new Turing entry I have written for the British Dictionary of National Biography.

Alan Turing's family origins and childhood
the inspiration of Christopher Morcom in his early life
the Turing Machine, foundation of modern computer science
his critical codebreaking work in the Second World War
the consequent emergence of his electronic computer plan, and its failure
the first working computer, the Turing Test, and biological growth
his arrest, trial, punishment, Cold War situation, new ideas and sudden death.


Now browse on to find out much more in...

The Alan Turing Internet Scrapbook

Here the emphasis is on links with other Internet sites, supported by many extra pictures and comments from my own resources. It is not complete or consistent in style and like the Internet will be in perpetual development.

Alan Turing was himself very informal in manner, even though precise in ideas. The Scrapbook style reflects not only the seriousness and tragedy of his life and work, but also its humour and unconventionality and prophetic sense for the modern world he did not live to see.

The Scrapbook now runs over twelve pages, full of facts and pictures and links:

Alan Turing's early life and consciousness
Turing Machines, with a Turing Machine Simulated in Java
Critical Cryptanalysis in the Second World War
Turing's Treatise on the Enigma (secret until 1996)
Who invented the computer?
Turing at Manchester, 1948-1950
The Turing Sex Test
Growth, form and crisis, 1951-1952
Wondrous Light, 1952-1954
Robin Gandy (1919-1995)
Breaking the Code (the play and TV film based on my book)


There is very much more about Alan Turing in my book:

Alan Turing: the Enigma

Please respect the work which has gone into this Site.

If you do more than read the material, for instance by using it for a student project, you should reciprocate by ordering, or getting your library to order, a copy of my book.

Alan Turing as a philosopher

I have written a new 58-page text on Alan Turing as a philosopher of Mind.

It is Turing, no. 3 of a series on The Great Philosophers published by Phoenix (London) in November 1997.

It gives a fresh look at the Turing machine, computability and the Turing test.
