Alan Turing

Alan Turing


Alan Turing, who was famous mathematician and World War II cryptanalyst, working for the British government born on June 23, 1912, In London, England.

Family Background:

He was born to Julius Mathison Turing and Ethel Sara Stoney. His father was employed with the ‘Indian Civil Service’. Alan had one sibling John Turing.

Personal Life:

In 1941, He had proposed to Joan Clarke, Who had been his colleague at Bletchley Park. The two got engaged, but the marriage had been soon called off when Turing decided it was unfair getting married to Clark despite being homosexual.

At the age of 39, He got into a relationship with 19-year-old, Arnold Murray.


He had continued his elementary education from ‘St Michael’s’, later he had to study at the ‘Sherborne School’ in Dorset, starting from 1926. In 1931, He had attended ‘King’s College’ at the ‘University of Cambridge’, graduating in mathematics three years later with top scores. In 1935, He had begun continuing a fellowship from ‘King’s College’.

During 1936-38, He had been taught at the ‘Princeton University’, by famous American logician, Alonzo Church. Along with lessons in mathematics, Alan had also been taught cryptology, and towards the end of this period, He was able to get his Ph.D. from the university. After this, He had also been taught by Ludwig Wittgenstein, at the ‘University of Cambridge’.


In September 1938, Turing had taken up a part-time job at the ‘Government Code and Cypher School’ (‘GC&CS’), an industry that specialized in breaking war codes which had been located at Bletchley Park during the World War II, and had been  there that Alan had attended by fellow code-breaker Dilly Knox. The modern mathematician had been appointed to break the codes sent by German officials, during World War II, through the radio machine, ‘Enigma’. In December 1939, He had developed a decrypting technique using statistical analysis and called it the ‘Banburismus. The ‘Banburismus’ had the potential to reveal the ‘Enigma’ codes, which had been more difficult than those used by other warring countries. In 1942, The brilliant mathematician had gone to the United States to study the methods of teaching the ‘Naval Enigma’ codes being employed by scholars at the ‘Computing Machine Laboratory’, in Dayton, Ohio. During 1945-47, Turing had started working at the ‘National Physical Laboratory’ (NPL), Where He produced a machine called the ‘Automatic Computing Engine’ (ACE). Around the same time, Alan had produced a research paper outlining his conception of the computer that could hold pre-fed programs. In 1948, He had started working at ‘Computing Laboratory’ initiated by mathematician Max Newman, located in the ‘University of Manchester’. He had developed the ‘Turing Test’, which can decide whether a machine is “intelligent” or not. In 1950, The chess program was built, with Champernowne’s help, and had been named ‘Turochamp’.

On 8 June 1954, Turing’s housekeeper found him dead, It was concluded that he had taken his own life by using large quantities of potassium cyanide.

Unknown Facts:

  • Alan Mathison Turing is his full name.
  • He was often called the father of modern computing.
  • He broke the rules to write to Churchill.

Master Stroke:

  • In 2002, Turing had been ranked twenty-first on the BBC nationwide poll of the 100 Greatest Britons.

Awards and Achievements:

  • In 1939, He had been awarded the ‘Smith’s Prize’.
  • In 1945, He had been honored by King George VI, with the ‘Most Excellent Order of the British Empire’, for his services during World War II.

What Can We Learn from Him??

Like Alan Turing, Always Give respect to women. Always ready to learn new things.
