Where are the leaders of today
I'm not really a history buff but I do like to read about WWII and started reading about Vannevar Bush, no relation to any of the former president's but he was the driving force behind winning WW2 through technology.
As director of the Office of Scientific Research and Development (OSRD) in 1941 he oversaw and directed 30,000 men and oversaw development of some 200 weapons and instrumentalities of war, the Manhattan Project, sonar, radar, the proximity fuze, amphibious vehicles, the Norden bomb sight. At one time, two-thirds of all the nation’s physicists were working under Bush’s direction. In addition, many advances of the physical sciences and medicine, including the mass production of penicillin and sulfa drugs.
He founded the company that later became Ratheon, his leadership created the National Science Foundation.
