Scientist who cloned Dolly the sheep dies


Keith Campbell, a British cell biologist who helped usher into being one of the most famous animals in creation, Dolly the cloned sheep, died last Friday at his home in Derbyshire. He was 58. His death was announced by the University of Nottingham, where he had taught since 1999. The cause was not made public.

In February 1997, Mr Campbell and his colleague Ian Wilmut, both then on the staff of the Roslin Institute, a research centre near Edinburgh, disclosed that Dolly, the first mammal to be cloned from an adult animal, had been born in Scotland the summer before.

The announcement, which seized the attention of the world media, was divisive. On the one hand, the experiment engendered great excitement for defying conventional scientific belief. On the other, it gave rise to concerns that the cloning of human beings was not far behind.
