Washington: Legendary Broadway songwriter Stephen Sondheim, widely recognized as having revolutionized American musical theater, died Friday at age 91, his lawyer told The New York Times. F. Richard Pappas said Sondheim — known for musicals including “West Side Story” — died suddenly at his home in Roxbury, Connecticut, the day after celebrating Thanksgiving with friends. Born on March 22, 1930 in New York City, Sondheim was involved in musical theater from an early age. He started playing piano at age seven and was family friends with Oscar Hammerstein II, half of the famed musical theater writing duo Rodgers and Hammerstein who wrote shows including “Oklahoma!” and “The Sound of Music.” Over the course of his decades-long career, Sondheim won eight Grammy awards, eight Tony awards — including the special Lifetime Achievement in the Theatre — and one Academy Award. He was nominated for many more Grammys and Tonys, as well as two Golden Globes. In 2015, then-US president Barack Obama presented Sondheim with the Presidential Medal of Freedom for his work.
