Lewis Wolpert

Lewis Wolpert is a distinguished scientist -and a familiar lanky figure on his bicycle, cycling through the Bloomsbury traffic to University College London where he is Emeritus Professor of Biology.

His scientific research has been into the early development of the embryo, but he's a man with many other interests ? he's written books about depression, and recently a book about getting old ? and he's currently bravely embarking on a book about the biological differences between the brains of men and women.

He talks to Michael Berkeley about the happiness he feels in his eighties, and about his early life, and his decision to leave South Africa where he was brought up to be a 'nice Jewish boy'. His choices are wide-ranging: from Noel Coward and Frank Sinatra to a late Beethoven Quartet and Wagner.
