Abstract :
F.C. Williams spent his whole professional life in inventive research. He defined invention as a forward step which is not taken as the result of logical processes on the available data. In his career there were many such forward steps, including inventing circuits for aircraft identification using radar, the computer storage medium used extensively in the early days of computer memory, the structure of the operational amplifier, variable-speed machines and speed control systems. This paper descibes the work of F.C. Williams
