Hollywood and Broadway are mourning the loss of composer Marvin Hamlisch.

The 68-year-old created the music behind some of Broadway's greatest hits, including the musical "A Chorus Line" and several of Hollywood's biggest films like, "The Way We Were."

"He was a true musical genius, but above all that, he was a beautiful human being. I will truly miss him," said Barbra Streisand, who first met the composer in 1963 and sang his "The Way We Were" to a Grammy win in 1974.

In four decades, Hamlisch won three Oscars, four Grammys, and three Golden Globe Awards.

Hamlisch collapsed and died Monday in Los Angeles after a brief illness, according to his publicist Ken Sunshine.

The composer was scheduled to fly to Nashville later this week to see a production of his musical "The Nutty Professor."

Hamlisch is survived by his wife of 25 years, Terre.
