Vannevar Bush was an American engineer, inventor, physicist, and science administrator who was instrumental in swift advance of scientific research and development of weapons during WWII. Born and raised in Massachusetts, he earned his B.S. and M.S. from ‘Tufts University,’ and a doctorate in electrical engineering from ‘MIT’ and ‘Harvard University.’ A pioneer in analog computers, he constructed a ‘differential analyzer’ that could solve equations with as many as 18 independent variables. He theorized a device that could be used to compress and store data. He called it ‘Memex,’ which later proved inspirational for those who worked on hypertext and digital computers. He invented several devices and registered 49 electronic patents. Bush was the scientific advisor to the US President and the Federal government during WWII. He led the ‘National Defense Research Committee (NDRC),’ and then served as director of the ‘Office of Scientific Research and Development’ (OSRD). He was also chairman of the ‘National Advisory Committee for Aeronautics’ (NACA). As chairman of the OSRD and the NDRC, he initiated the crucial ‘Manhattan Project.’ He authored a number of books and is known for his articles ‘As We May Think,’ and ‘Science, the Endless Frontier.’
