Sir Ian Wilmut, OBE FRS FMedSci FRSE (7 July 1944 – September 2023) was a prominent British embryologist who left an indelible mark on the field of regenerative medicine. Serving as the Chair of the Scottish Centre for Regenerative Medicine at the University of Edinburgh, he gained worldwide recognition for cloning the first mammal from an adult somatic cell—a Finnish Dorset lamb named Dolly. Alongside a slew of awards and honors, Wilmut co-authored books and contributed to advancements in stem cell research.

Early Life and Education

Born in Hampton Lucy, Warwickshire, England, Wilmut was the son of Leonard Wilmut, a mathematics teacher afflicted with diabetes, which eventually led to his blindness. Ian Wilmut studied at the Boys’ High School in Scarborough, where his father taught. Initially aspiring for a naval career, he was unable to pursue this path due to color blindness.

During his school years, Wilmut worked as a farm hand on weekends, which inspired him to study Agriculture at the University of Nottingham. In 1966, he worked under Christopher Polge, renowned for his work on cryopreservation. Eventually, Wilmut pursued a Doctor of Philosophy degree at the University of Cambridge, graduating in 1971 with a thesis on semen cryopreservation. He was a postgraduate student at Darwin College, Cambridge during this period.

Career and Research

Following his PhD, Wilmut focused on research concerning gametes and embryogenesis and worked at the Roslin Institute. He led the groundbreaking research that culminated in the cloning of Dolly in 1996, a feat that catapulted him to global fame. However, Dolly died in 2003 due to a respiratory disease.

In 2008, Wilmut shifted his focus towards a technique developed by Shinya Yamanaka, which involved deriving pluripotent stem cells from differentiated adult skin cells. This approach, he believed, held the promise of treating degenerative diseases like Parkinson’s. Although he led the team that created Dolly, he later acknowledged that his colleague Keith Campbell deserved significant credit for the invention.


In 2006, Wilmut co-authored the book “After Dolly: The Uses and Misuses of Human Cloning” with Roger Highfield.

Awards and Honours

Among the many accolades he received, some notable ones include:

  • Lord Lloyd of Kilgerran Award in 1998
  • Golden Plate Award of the American Academy of Achievement in 1998
  • Appointed Order of the British Empire (OBE) in 1999
  • Elected Fellow of the Royal Society (FRS) in 2002
  • Elected Fellow of the Academy of Medical Sciences in 1999
  • Elected EMBO Member in 2003

Wilmut was also knighted in the 2008 New Year Honours for his services to science and was a runner-up for Time magazine’s Man of the Year in 1997.


Sir Ian Wilmut passed away in September 2023, at the age of 79.


Wilmut’s work continues to influence the fields of regenerative medicine, cloning, and stem cell research. His pioneering efforts have left an everlasting impact, laying the groundwork for future explorations in medical science.
