F. C. Brown Papers
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. He invented the phonopticon, an improvement on the optophone (invented by Fournier d'Albe, 1912). Material focuses on Dr. Brown's professional life: correspondence, photographs, photo albums, scrapbooks, and ephemera from the positions he held and research he conducted. Very little personal information is included.
