Plaques in Hampstead
Gerald Swyer (1917-1995)
Gerald Swyer pioneered many advances in reproductive medicine including the development of the contraceptive pill in the 1950s. Later, many women who would have remained childless, were able to conceive thanks to his extraordinary work on fertility. The development of hormone replacement therapy, and the identification of a rare genetic condition which became known as Swyer Syndrome, are all a critical part of his enduring legacy.
