Description: ISBN10: 1107020581, ISBN13: 9781107020580, [publisher: Cambridge University Press] Hardcover Druck auf Anfrage Neuware - Printed after ordering - '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. The contrast between this memoir and the original biography reveals tensions and sheds new light on Turing's relationship with his family, and on the man himself. 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. [Einbeck, Germany] [Publication Year: 2012]
