Alan M. Turing by Sara Turing, Centenary Edition

Alan M. Turing

By Sara Turing

With a new afterword by John Turing

And a foreword by Martin Davis

Published 29 March 2012

210 pages, £17.99

To commemorate the centenary of Turing's birth his mother's fascinating biography, unavailable for years, is here republished with a new foreword and a never-before published memoir by Alan Turing's older brother.

'An even-tempered, lovable character with an impish sense of humour.' 'In a short life he accomplished much, and to the roll of great names in the history of his particular studies added his own.' So is described one of the greatest figures of the twentieth century, yet Alan Turing's name was not widely recognised until his contribution to the breaking of the German Enigma code became public in the 1970s. The story of Turing's life fascinates and in the years since his suicide, Turing's reputation has only grown, as his contributions to logic, mathematics, computing, artificial intelligence and computational biology have become better appreciated.

To commemorate the centenary of Turing's birth, this republication of his mother's biography is enriched by a new foreword by Martin Davis and a never-before published memoir by Alan's older brother, which sheds new light on Alan's relationship with his family and on the man himself - from offering 'theories' for why Alan was gay (a fact his mother's biography fails to mention) to commenting on the constantly disgusting state of his fingernails.
