George Dyson's fascinating account of the early years of computers: "Turing's Cathedral" is the story behind how the PC, ipod, smartphone and almost every aspect of modern life came into being. In 1945 a small group of brilliant engineers and mathematicians gathered at the Institute for Advanced Study in Princeton, determined to build a computer that would make Alan Turing's theory of a 'universal machine' reality. Led by the polymath emigre John von Neumann, they created the numerical framework that underpins almost all modern computing - and ensured that the world would never be the same again. George Dyson is a historian of technology whose interests include the development (and redevelopment) of the Aleut kayak. He is the author of "Baidarka"; "Project Orion"; and "Darwin Among the Machines". "Unusual, wonderful, visionary". (Francis Spufford, "Guardian"). "Fascinating... the story Dyson tells is intensely human... a gripping account of ideas and invention. Fascinating... the story Dyson tells is intensely human... a gripping account of ideas and invention. " ("Jenny Uglow"). "Glorious... as much a story of the personalities involved as of the discoveries they made, and you do not need any knowledge of computers or mathematics to enjoy the ride... a ripping yarn". (John Gribbin, "Literary Review").
