Charles Edward Durning was born into poverty on Feb. 28, 1923, in Highland Falls, N.Y., a Hudson River village. His father, James, an Irish immigrant, had been sickened by mustard gas and lost a leg in World War I and died when Charles was 16. Charles was the ninth of 10 children, and five of his sisters died of smallpox or scarlet fever in childhood, three of them within two weeks.

Never a good student, young Charles dropped out of school and eventually left for Pennsylvania, deciding that his mother, Louise, a laundress at the United States Military Academy at West Point, would fare better with one less mouth to feed. He worked as a farmhand and did other menial jobs before moving to Buffalo, where again he took odd jobs. One, opportunely, was as an usher in a burlesque house.

One night a frequently drunk comedian failed to show up, and Mr. Durning, who had memorized the comic’s jokes, persuaded the manager to let him go on. He “got laughs,” he later recalled, and was “hooked” on show business. He made his stage debut in Buffalo.

Then came World War II, and he enlisted in the Army. His combat experiences were harrowing. He was in the first wave of troops to land on Omaha Beach on D-Day and his unit’s lone survivor of a machine-gun ambush. In Belgium he was stabbed in hand-to-hand combat with a German soldier, whom he bludgeoned to death with a rock. Fighting in the Battle of the Bulge, he and the rest of his company were captured and forced to march through a pine forest at Malmedy, the scene of an infamous massacre in which the Germans opened fire on almost 90 prisoners. Mr. Durning was among the few to escape.

By the war’s end he had been awarded a Silver Star for valor and three Purple Hearts, having suffered gunshot and shrapnel wounds as well. He spent months in hospitals and was treated for psychological trauma.
