Barry Cooper, Professor of Pure Mathematics at Leeds and Chair of the Turing Centenary Advisory Committee, writes in the Guardian a personal account of an interest in Turing and his efforts to get the limited edition biography written by Turing’s mother Sara republished.
Written from a mother’s viewpoint, Sara provides a unique insight into the early years of Turing, with candid descriptions such as, “In dress and habits he tended to be slovenly. His hair was usually too long, with an overhanging lock which he would toss back with a jerk of his head.” But the book is full of brilliant treasures, anecdotal accounts of Turing’s eccentricity and genius, and insights into his science.
