Simon Singh is a science journalist and TV producer. Having completed his PhD at Cambridge he worked from 1991 to 1997 at the BBC producing Tomorrow's World and co-directing the BAFTA award-winning documentary Fermat's Last Theorem for the Horizon series. In 1997, he published Fermat's Last Theorem, which was a best-seller in Britain and translated into 22 languages.
Secret writing has been altering the course of history for thousands of years - from ancient Chinese messages written on silk, wrapped up, covered in wax and swallowed by the courier to today's quest for the ultimate, unbreakable code. Likening codes to bacteria and codebreakers to antibiotics, the author of the acclaimed Fermat's Last Theorem examines what he describes as the 'evolution' of cryptography. This isn't a definitive history, rather Singh adopts an absorbing magpie approach, using snippets of history to illustrate his points, interspersed with examples of cryptanalysis. With information as valuable as ever, and ever easier to intercept and abuse, he makes a plea for the continuing importance of codes as a way of protecting our privacy. (Kirkus UK)
