Born on March 22, 1930 in New York City, Sondheim was involved in musical theater from an early age.
He began playing the piano at age seven and was a family friend of Oscar Hammerstein II, a member of the famous musical theater duo Rodgers and Hammerstein, who wrote works such as ¡Oklahoma! and The Sound of Music (The rebellious novice).
Sondheim (New York, 1930), winner of an Oscar, a Pulitzer, and more than fifteen Emmys and Grammys, began to reap success in the late 50s, when he wrote the lyrics for Gypsy, and continued to triumph until the 90s, with the lyrics and music of Assasins, with which he gave a voice to the people who killed or tried to kill a US president.
The first work in which he composed both music and lyrics was the 1962 comedy A Funny Thing Happened on the Way to the Forum, which won a Tony and was represented for more than two years on Broadway.
In the 70s and 80s, his most productive years, he produced works considered varied and original, including Company (1970), Follies (1971), A Little Night Music (1973), Pacific Overtures (1976), Sweeney Todd (1979), Merrily We Roll Along (1981) e Into the Woods (1987).
Total, Sondheim composed both the lyrics and the music for 12 Broadway shows, of which five won a Tony for best musical, and six of them a Tony for best soundtrack, while the show Sunday in the Park, which did not receive either of those two awards, it was awarded a Pulitzer.
