Richard Francis Lyon

Richard Francis Lyon (born 1952), is an American inventor, scientist, and engineer, noted for having invented the optical mouse.[1][2][3] He has worked in many aspects of signal processing and was a co-founder of Foveon Inc., a digital camera and image sensor company.

Life[edit]

Lyon grew up in El Paso, Texas, one of nine children. He received a B.S. from Caltech in 1974 and an M.S. in Electrical Engineering from Stanford University in 1975.

Lyon has worked at a number of Silicon Valley companies, including Stanford Telecommunications, Xerox, Schlumberger, Apple, Foveon, and Google.

Inventions and research[edit]

In 1981, Lyon built the first optical mouse, at Xerox,[4] for which he was awarded two U.S. patents, now expired.[5][6]

He also did pioneering work in the following areas:
