Hypertext Pioneer Vannevar Bush Is Born

Pre-World War II computer pioneer Vannevar (pronounced "Van-ee-ver") Bush is born in Everett, Massachusetts. Bush, who also was deeply involved with wartime computer projects, invented an electromechanical differential analyzer that used mechanical integrators to help solve differential equations. Bush was a co-founder of Raytheon, a military contractor. He also became very interested in information retrieval, which led him to imagine a machine he called "memex" -- an electronic extension of an individual's mind and memory base -- that mimicked human associative linking of information, and anticipated hypertext research. He died on June 28, 1974.
