The department of Computer Science and Technology was founded in 1937 (as the Mathematical Laboratory, and later the Computer Laboratory) for work on mechanical calculators and analogue computers. It became involved in digital computing after 1945 under the direction of Professor Maurice Wilkes. Some of the Cambridge developments of that period belong in the basic stock of computing knowledge, for example the ideas of subroutines and of microprogramming.
