British computer scientist credited with several important contributions in computing. He developed the idea of microprogramming in which the central processing unit (CPU) could be controlled by a miniature, highly specialised computer programming in high-speed ROM. Wilkes and his team also came up with the concepts of subroutine libraries and macros which made programming much easier. This greatly helped in the development of high-level programming languages. He is, however, best remembered for his work on the EDSAC (Electronic delay storage automatic calculator) which was built in his laboratory.
