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. This bok is the story behind how the PC, ipod, smartphone and almost every aspect of modern life came into being.

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 émigré 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.

'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
