Lewis Frederick Crabtree obtained in 1945 the BSc title from the University of Leeds in mechanical engineering, and later was graduated in aeronautics at Imperial College, London. Crabtree then gained the PhD title from the Cornell University, USA, in aeronautical engineering. He moved in the 1950s to the Farnborough Royal Aircraft Establishment as a research engineer. He there headed from 1966 the propulsion aerodynamics and noise department after engagement in the hypersonic and high temperature gas dynamics division. Crabtree was appointed in 1973 professor of aeronautical engineering at Bristol University. Crabtree presided over the Royal Aeronautical Society, London in 1978- 79 and later was one of its Honorary Members. He was also an Honorary Member of the American Institute of Aeronautics and Astronautics AIAA.

\

The scientific interests of Crabtree were in aeronautical engineering and aerodynamics. He contributed a number of books to the profession, among which one is Hypersonic aerodynamics published in 1965 in collaboration with a colleague, a book entitled Laminar boundary layers in which the basic knowledge up to 1960 was summarized, and the Incompressible aerodynamics published in 1959 as the co-author. Crabtree was the Editor of the Journal Aeronautical Quarterly from 1977 to 1984 and he served as an Associate Editor for the Aeronautical Journal from 1985.
