Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American actor, comedian, and director. He is best known for his silent film work, in which his trademark was physical comedy accompanied by a stoic, deadpan expression that earned him the nickname "The Great Stone Face". Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929" when he "worked without interruption" as having made him "the greatest actor-director in the history of the movies". In 1996, Entertainment Weekly recognized Keaton as the seventh-greatest film director, writing that "More than Chaplin, Keaton understood movies: He knew they consisted of a four-sided frame in which resided a malleable reality off which his persona could bounce. A vaudeville child star, Keaton grew up to be a tinkerer, an athlete, a visual mathematician; his films offer belly laughs of mind-boggling physical invention and a spacey determination that nears philosophical grandeur." In 1999, the American Film Institute ranked him as the 21st-greatest male star of classic Hollywood cinema.
Working with independent producer Joseph M. Schenck and filmmaker Edward F. Cline, Keaton made a series of successful two-reel comedies in the early 1920s, including One Week (1920), The Playhouse (1921), Cops (1922), and The Electric House (1922). He then moved to feature-length films; several of them, such as Sherlock Jr. (1924), The General (1926), Steamboat Bill, Jr. (1928), and The Cameraman (1928), remain highly regarded. The General is viewed as his masterpiece: Orson Welles considered it "the greatest comedy ever made...and perhaps the greatest film ever made". Welles said Keaton "was beyond all praise...a very great artist, and one of the most beautiful men I ever saw on the screen. He was also a great director. In the last analysis, no one came near him." In 2018, Peter Bogdanovich released The Great Buster: A Celebration, a tribute to Keaton featuring Mel Brooks, Carl Reiner, Werner Herzog and Quentin Tarantino, among others.
