Lewis Wolpert is a distinguished embryologist and an accomplished broadcaster. He is Professor of Biology as Applied to Medicine at University College, London, and has taken part in numerous radio programmes, particularly interviews with other scientists. A CBE and a Fellow of the Royal Society, he was chairman of the Committee on the Public Understanding of Science for four years.He is the author of A Passion for Science and Passionate Minds (with Alison Richards), and The Triumph of the Embryo. For Faber, he has written The Unnatural Nature of Science: 'I can think of no book which explains science better or more vigorously to the layman. Professor Wolpert's prose is clear, direct, and euphonious; it seems almost unfair that he should be an eminent scientist as well.' (Spectator).
