Computer science development of sophisticated computing equipment. Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623. In 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner. He may be considered the first computer scientist and information theorist, for, among other reasons, documenting the binary number system. In 1820, Thomas de Colmar launched the mechanical calculator industry when he released his simplified arithmometer, which was the first calculating machine strong enough and reliable enough to be used daily in an office environment. Charles Babbage started the design of the first "automatic mechanical calculator", his Difference Engine, in
Mike Keith (mathematician) Mike Keith (mathematician) Michael Keith (born 1955) is an American mathematician, software engineer, and author of works of constrained writing. Keith was employed at Sarnoff Corporation from 1980 until 1990 and Intel Corporation from 1990 to 1998, both tenures involving work in multimedia software. He was part of the original team at Sarnoff that developed Digital Video Interactive, the first PC digital video system, and at Intel he was a member of the group that developed Indeo, another video compression standard. As a result of this work Keith is credited as inventor or co-inventor on 60 US patents. he works
