# Michael Berry (physicist)

Sir Michael Victor Berry (born 14 March 1941 in Frimley) is a British theoretical physicist. He is the Melville Wills Professor of Physics (Emeritus) at the University of Bristol.
He is known for the Berry phase, a phenomenon observed in both quantum mechanics and classical optics, as well as Berry connection and curvature. He specializes in semiclassical physics (asymptotic physics, quantum chaos), applied to wave phenomena in quantum mechanics and other areas such as optics.

## Early life and education

Berry was brought up in a Jewish family and was the son of a London taxi driver and a dressmaker. Berry earned a BSc in physics from the University of Exeter in 1962 where he met his first wife (a sociology student with whom he had his first child) and a PhD from the University of St. Andrews in 1965. His thesis is titled The diffraction of light by ultrasound.

## Career and research

He has spent his whole career at the University of Bristol. He was a research fellow, 1965–67; lecturer, 1967–74; reader, 1974–78; Professor of Physics, 1978–88; and Royal Society Research Professor 1988–2006. Since 2006, he has been Melville Wills Professor of Physics (Emeritus) at Bristol University.

## Awards and honours

He was elected a Fellow of the Royal Society (FRS) in 1982 and knighted in 1996. From 2006 to 2012 he was editor of Proceedings of the Royal Society A.
