Richard Grimsdale

Richard Lawrence Grimsdale (18 September 1929 to 6 December 2005) was a British electrical engineer and computer pioneer who helped design the world's first transistorized computer. As a postgraduate researcher at the University of Manchester he designed and developed the Metrovick 950 in 1953, the first computer built from transistors rather than valves or mechanical components, and he also contributed to the Ferranti Mark I, a commercial computer based on the Manchester Mark 1, and engineered a 100 nanosecond read only memory component for the later Atlas computer. He went on to work at Associated Electrical Industries and the University of Sussex, where his research expanded into computer graphics and networking.
