Sir Ian Wilmut

Sir Ian Wilmut was born in Warwickshire, England, and studied agricultural science at the University of Nottingham before completing a PhD on the freezing of boar semen at Darwin College, Cambridge. He joined the Roslin Institute near Edinburgh in the early 1970s, where he pioneered techniques in cryopreservation and genetic manipulation of livestock embryos.

In 1996, Wilmut and his colleague Keith Campbell achieved a scientific breakthrough that astonished the world: using nuclear transfer from an adult mammary gland cell into an enucleated ovum, they produced Dolly the sheep. The feat proved that specialized adult mammalian cells could be reprogrammed back to an embryonic totipotent state, overturning decades of biological dogma. The breakthrough paved the way for regenerative medicine and stem-cell therapies. Wilmut was knighted in 2008 and later established the Centre for Regenerative Medicine at the University of Edinburgh.
