Actor Jack Lemmon, the two-time Oscar winner, has died at 76.
He died from complications related to cancer, his spokesman Warren Cowan said.
His wife Felicia and two of his children were at his bedside at USC/Norris Cancer Clinic in Los Angeles.
"He is one of the greatest actors in the history of the business," Mr Cowan said.
"To say one word about him would be beautiful. It's an opinion that is shared by everybody who knew him."
Lemmon was known best for films such as Some Like It Hot, Days of Wine and Roses and Tuesdays with Morrie.
The Harvard-educated actor began in films with two stylish comedies and a musical with Betty Grable.
Then in 1955, he showed his unique comedy style as the hapless Ensign Pulver in Mister Roberts, a role that won him an Oscar as supporting actor.
Throughout his career, and especially in films with Walter Matthau, Lemmon was often cast as the well-meaning fellow, a trifle square, who is taken advantage of by more forceful individuals.
In The Fortune Cookie, he is browbeaten into filing a false insurance claim by his brother-in-law.
The Odd Couple portrayed Lemmon as the fastidious Felix Unger, who suffers from the slobbish habits of his room-mate, Oscar Madison (Matthau).
In The Front Page, city editor Matthau tricks his star reporter, Lemmon.
In 1962, Lemmon made a complete switch from his string of light-hearted comedies.
In Days of Wine and Roses, he played an alcoholic who induces his new wife (Lee Remick) to join him in drinking sprees.
His intense performance surprised critics and audiences and brought his first Academy nomination as lead actor.
