Dolly (sheep)
Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep, and the first mammal cloned from an adult somatic cell, using the process of nuclear transfer.
Ian Wilmut
Wilmut led the team that created Dolly, but in 2006 admitted his colleague Keith Campbell deserved "66 per cent" of the invention that made Dolly's birth possible, and that the statement "I did not create Dolly" was accurate. His supervisory role is consistent with the post of principal investigator held by Wilmut at the time of Dolly's creation.
