Sidney Poitier, whose portrayal of resolute heroes in films like "To Sir, With Love,” "In the Heat of the Night” and "Guess Who’s Coming to Dinner” established him as Hollywood’s first Black matinee idol and helped open the door for Black actors in the film industry, died Thursday night at his home in Los Angeles. He was 94.

His death was confirmed by Eugene Torchon-Newry, acting director general of the Ministry of Foreign Affairs in the Bahamas, where Poitier grew up. No cause was given.

Poitier, whose Academy Award for the 1963 film "Lilies of the Field” made him the first Black performer to win in the best-actor category, rose to prominence when the civil rights movement was beginning to make headway in the United States. His roles tended to reflect the peaceful integrationist goals of the struggle.
