Richard Prelinger is a archivist of films you probably thought were not worth saving: educational, industrial, and public-service films made from the 1930s through the 1960s.

The former head of NBC's television programming Pat Weaver (Sylvester L. "Pat" Weaver, Jr.). He began that job in the early days of the medium - in 1949 - and was the creator of two of television's longest running shows, the "Today" show and the "Tonight" show. Weaver started his career in radio, where he worked with comic Fred Allen. And he was advertising manager for the American Tobacco Company, under the eccentric tobacco magnate George Washington Hill. Weaver has a new memoir of his career, "The Best Seat in the House," (Knopf).
