Roger George Kennedy (August 3, 1926 – September 30, 2011) was an American polymath whose career included banking, television production, historical writing, and museum administration, the last as director of the Smithsonian Institution's National Museum of American History, before the Bill Clinton administration selected him to head the National Park Service in 1993. He was especially concerned about expanding the service's educational role and moved to enlarge its presence beyond the parks via the Internet.
