Sophie Wilson is a British computer scientist known for designing the instruction set of the ARM RISC-processor. This processor nowadays is an important part of most mobile devices, as it makes tablets and smartphones faster and more energy efficient.  She studied University of Cambridge and during her time as a student already developed a machine to automate cattle feeding as well as an 8-Bit-Microprocessor for Acorn. Later on, she and Steve Furber built a microcomputer for the BBC while working at Acorn.

Sophie has been named a Fellow of the Computer History Museum and was accepted into the Royal Society. Maximum PC (http://www.maximumpc.com/) in 2011 named her one of the 15 most important women in computer history. The picture shows poster printed by the german “Gesellschaft für Informatik” (https://en.gi.de/) as part of the series “faces of computer science”, detailing her career. Other persons featured in the poster series are Alan Turing, Ada Lovelace, Joseph Weizenbaum and Grace Hopper.
