'The book is full of brilliant treasures, anecdotal accounts of Turing's eccentricity and genius, and insights into his science … This little book, with its kaleidoscopic picture of Alan Turing's short life, goes some way towards de-coding his mind, and his family.' The Guardian
'Well-written and tackles some of Turing's mathematical work.' Engineering and Technology
'… the readers of the new edition can benefit from a previously unpublished memoir by Alan's older brother John, as well as a new foreword by Martin Davis; both texts provide a different view of Alan Turing, and represent a nice complement to the main part of the book.' Antonin Slavik, Zentralblatt MATH
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.
