From Publishers Weekly
Hounded by authorities and peers alike, British mathematician Alan Turing committed suicide in 1954 by biting into a cyanide-laced apple. A groundbreaking thinker in the field of pure math, a man principally responsible for breaking the Enigma code used by the Germans during WWII and the originator of the ideas that led to the invention of the computer, Turing was also an avowed homosexual at a time when such behavior flew in the face of both convention and the law. Leavitt (The Body of Jonah Boyd) writes that the unfailingly logical Turing was so literal minded, he "neither glorified nor anthologized" his homosexuality. Educated at King's College, Cambridge, and Princeton, Turing produced the landmark paper "On Computable Numbers" in 1937, where he proposed the radical idea that machines would and could "think" for themselves. Despite his Enigma code–breaking prowess during the war, which gave the Allies a crucial advantage, Turing was arrested in 1952 and charged with committing acts of gross indecency with another man. With lyrical prose and great compassion, Leavitt has produced a simple book about a complex man involved in an almost unfathomable task that is accessible to any reader. Illus. (Nov. 28)

Initiated by the definitive biography Alan Turing, by Andrew Hodges (1983), the revival of the reputation of the computer theorist continues with this engaging treatment. Leavitt's signal accomplishment is a comprehensible explanation of the mathematical abstractions in Turing's seminal papers, "On Computable Numbers" (1936) and "Computing Machinery and Intelligence" (1950), from which derive the popular shorthand of the "Turing machine" and the "Turing test." On the biography side, Leavitt reveals a perceptive understanding of Turing's personality, one more sophisticated than the common view of Turing as a martyr to homophobia. Arrested for an infraction of a law against homosexuality, Turing committed suicide at age 42 in 1954. Its peculiar manner--Turing ate a cyanide-laced apple--induces Leavitt to integrate Turing's obsessions with the film Snow White, with an apparently unrequited love interest who died in Turing's teens, and with ESP into an unconventional speculation. Turing is the model of the solitary, absentminded genius. His tragedy and his intellectual significance, including his role in breaking German ciphers in World War II, come clear in Leavitt's hands.

Too much math, too little man behind the math.
Turing's best-known accomplishments, his work in code breaking and in developing the computer, were not as dramatically presented in this book as I would have liked. I was hoping for the book to promote Turing; to bring him forward and upward into the limelight. Instead it leads the reader down into the minutiae of Turning's mathematics and his homosexuality. Consequently the co-tragedies of his persecution and suicide, the ultimate irony of a society killing the man who saved it, were not as strongly or as dramatically presented as they might have been.
In fairness to the author, Mr. Leavitt probably told Alan Turing's story as Mr. Turing would have told it, himself. Rather than writing the promotional piece for Turning that I expected and wanted, Mr. Leavitt emphasized the mathematical challenges, achievements and social forces that shaped this brilliant man. Someone picking up this book to read about a mathematician and his work should find great interest in the details, the very details that for me were more of a distraction.
