On March 11, 1890, American engineer, inventor and science administrator Vannevar Bush was born. He is best known as as head of the U.S. Office of Scientific Research and Development (OSRD) during World War II, through which almost all wartime military research and development was carried out, including initiation of the Manhattan Project. In computer science we know Vannevar Bush as the father of the memex, an adjustable microfilm viewer with a structure analogous to that of the World Wide Web.
