F.C. Brown was a physicist and inventor who created and supervised the development of education exhibits, most notably as organizing director of the New York Museum of Science and Industry (part of the Museums of the Peaceful Arts), 1926-1931. He was also curator of physics exhibits at Chicago's Museum of Science and Industry, 1932-1937. Much of Brown's scientific research focused on the element selenium.
