Lewis Wolpert was raised in South Africa where he trained to become a civil engineer specializing in soil mechanics, which he abandoned for cell biology in 1955. “A friend told me that soil mechanics wasn’t very sexy and that some of my work could be relevant to the study of cell mechanics,” he says. After obtaining a PhD from University of London, King’s College, Wolpert focused on morphogenesis with a special interest in the pattern of limb formation. The author of many books, his latest include a new edition of the textbook Principles of Development (with Cheryll Tickle) and You’re Looking Well: The Surprising Nature of Getting Old.
