Alan Turing

以下信息来自The Alan Turing Home Page

Who was Alan Turing?
Founder of computer science, mathematician, philosopher, codebreaker, strange visionary and a gay man before his time.

在Turing的简短生平中,我选择了下面几条:
1912 (23 June): Birth, Paddington, London

二战期间，Turing曾进行过密码破解的工作，成功破解了德国的Enigma加密算法
1938-39: Return to Cambridge. Introduced to German Enigma cipher machine.
1939-40: The Bombe, machine for Enigma decryption.
1939-42: Breaking of U-boat Enigma, saving battle of the Atlantic.

1952: Arrested as a homosexual, loss of security clearance.
loss of security clearance应该是指失去了为国家情报部门工作的机会。
1954 (7 June): Death (suicide) by cyanide poisoning, Wilmslow, Cheshire.

I have to say, sometimes the world is weird.
