    Vannevar Bush - Engineer,Inventor&1st Sci Adv to the Pres/Manhattan Proj/Signed Note paper
    Vannevar Bush (1890-1974) - American engineer, inventor and science administrator, who during World War II  headed the U.S. Office of Scientific Research and Development (OSRD), through which almost all wartime military R&D was carried out, including important developments in radar and the initiation and early administration of the Manhattan Project. He emphasized the importance of scientific research to national security and economic well-being, and was chiefly responsible for the movement that led to the creation of the National Science Foundation.
    Bush joined the Department of Electrical Engineering at Massachusetts Institute of Technology (MIT) in 1919, and founded the company that became the Raytheon Company in 1922. Bush became vice president of MIT and dean of the MIT School of Engineering in 1932, and president of the Carnegie Institution of Washington in 1938.
    During his career, Bush patented a string of his own inventions. He is known particularly for his engineering work on analog computers, and for the memex . Starting in 1927, Bush constructed a differential analyzer, an analog computer with some digital components that could solve differential equations with as many as 18 independent variables. An offshoot of the work at MIT by Bush and others was the beginning of digital circuit design theory.
    4.5“ x 6“ personal note paper signed in fountain pen. Light scattered soiling with a faint transmittal fold, otherwise fine.
