"The world needed Alan Turing in the early years of computer science, and it still does."
Anthony L. Clapes, Computing Reviews
"The book does effectively portray both Alan Turing's life and work. I recommend this book not only to people interested in Alan's scientific achievements, but to anyone who woiuld like to meet a genius of the modern era."
Rita Puzmanova, Computing Reviews
"Turing appeals to many audiences. The book explains Turing's proof of the existence of a universal computing machine in a way that is understandable to readers with little background in mathematics or computer science, but it also includes a more mathematically sophisticated explanation that would satisfy readers with more background. Well written and engaging, Turing tells more than the tale of one man's life; it also explores the origins of modern computer science. Turing is a book worth reading."
Jessica Cohen, Western Washington University for Mathematics Teacher
To commemorate the centenary of Turing's birth, this republication of his mother's biography contains a new foreword by Martin Davis and a never-before-published memoir by Alan's brother. The contrast between this memoir and the original biography sheds new light on Turing's relationship with his family, and on the man himself.
