Abstract
Important developments in the theory and application of Quantum Chemistry during the period 1948-88, arising from work of theoretical chemists at the University of Cambridge, are discussed. The outstanding contributions of S.F. Boys are detailed, and the significance that this work of the 1950s had on quantum chemistry is recognized. A description of Boys' later work is also given. An outline of some of the contributions from Cambridge in the last ten years is also described. A list of names or researchers in quantum chemistry for the period is given. The advances which have been made are linked to the history of the development of the computer service, and this is discussed.
