Ian Wilmut, Scientist Behind Dolly the Cloned Sheep, Is Dead at 79 - Slashdot

The Roslin Institute , a research center near Edinburgh where Dr. Wilmut had worked for decades , said in a statement that the cause was complications of Parkinson's disease.

He led efforts to develop cloning, or nuclear transfer, techniques that could be used to make genetically modified sheep.

It was these efforts which led to the births of Megan and Morag in 1995 and Dolly in 1996 .

Polly, the first mammal to be both cloned and genetically modified, was born in 1997 .
