Education

Stuart was educated Gateway Grammar School, Leicester and Imperial College of Science and Technology, London where he was awarded a Bachelor of Science degree in 1949 and a PhD in 1953.

Career

Stuart joined the Aeronautics Division of the National Research Laboratory, returning to join the staff of Imperial College after a few years. He was appointed professor of theoretical fluid mechanics in 1966 and was head of the Department of Mathematics from 1974 to 1979 and 1983 to 1986. He was Dean of the Royal College of Science from 1990 to 1993. He is currently emeritus professor at Imperial.
