Andrew David Hamilton Wyllie FMedSci FRS[1] (1944 – 26 May 2022)[2] was a Scottish pathologist.
In 1972, while working with electron microscopes at the University of Aberdeen he realised the significance of natural cell death.
He left Edinburgh for a chair at Cambridge in 1998 where he continued to lecture to undergraduate medical and natural sciences students.
If apoptosis is for some reason prevented, it can lead to uncontrolled cell division and the subsequent development of a tumour.
After retirement, Wyllie was succeeded in his role as Head of the Department of Pathology at Cambridge by Geoffrey L. Smith in October 2011.
