Dapper and strong-willed electrical engineer and physicist at MIT. The iconic New England Yankee, Bush graduated from Tufts University in 1913. At MIT he developed the Differential Analyzer, an analog computer that could solve differential equations and was used during World War II to decipher code. In 1922 he cofounded the company that would become the high-tech giant Raytheon. From 1941 to 1945 he was director of the U.S. Office of Scientific Research and Development (OSRD), where he allocated funds to develop military technology, including the first atomic bomb and the radar. After the war he conceived the idea of the memex, an information storage device that would create associative links. His memex idea directly inspired Doug Engelbart, J. C. R. Licklider, and Ted Nelson.
