This biography tells the story of Alan Turning who worked with other scientists and mathematicians during World War II to develop a machines which could break the code in encrypted messages intercepted by the Allies. Turing has been called the father of modern day computing but his work was largely unknown during his lifetime due to the extreme secrecy of the code breaking activities at Bletchley Park. Participants were bound by the Official Secrets Act and could not tell their friends and family about the important role they played in the War effort. After the War Turing was persecuted for his sexuality and spent the last years of his life labelled as a degenerate and security risk.
Unfortunately despite its important content, this book was a tedious read. Clocking in at over 500 pages of dry biographical details including formulae, long scientific passages and boring descriptions of cryptography. Many of the Critics did not finish the book and much of the discussion at this meeting involved the Academy Award winning film based on this biography.
