Frederick Wiseman (January 1, 1930 — February 16, 2026) was an American filmmaker, documentarian, and theatre director. As a documentarian, Wiseman has been noted for his ability to capture the nuances of life in American institutions such as prisons, hospitals, welfare offices, and high schools. He started out in 1963 by producing a narrative crime drama, The Cool World, an examination of the lives of Harlem teenagers. In the beginning, Wiseman was a staunch social reformist, and his films were calls for change.

Titicut Follies, his first documentary, is an exposé of life in a prison for the criminally insane in Bridgewater, MA. It was controversial and left Wiseman with the reputation of being a muckraker. His four subsequent documentaries were exposés of other tax-supported institutions designed to show the ineffectiveness of the bureaucracy that not only threatens to destroy, but also dehumanizes the people they're meant to serve. Wiseman toned down his message and began focusing more on American culture to point out the symbolism of daily activities in his film Primate (1974).
