Sad…one of the most controversial innovators in science has passed away.
Keith Campbell has died at the age of 58, although the cause of death was not released by the biologist's employer, Nottingham University.
Campbell began researching animal cloning in 1991 and his experiments led to the birth of Dolly, a sheep clone named after Dolly Parton.
After Dolly, the biologist continues his research as a professor at Nottingham University and successfully cloned pigs and lambs.
