Kirk Douglas, one of the last surviving movie stars from Hollywood’s golden age, whose rugged good looks and muscular intensity made him a commanding presence in celebrated films like “Lust for Life,” “Spartacus” and “Paths of Glory,” died on Wednesday at his home in Beverly Hills, Calif. He was 103. His son the actor Michael Douglas announced the death. He was known for manly roles, in westerns, war movies and Roman-era spectacles, most notably “Spartacus” (1960). But in 80 movies across a half-century he was equally at home on mean city streets, in smoky jazz clubs and, as Vincent van Gogh, amid the flowers of Arles in the south of France. Many critics thought he should have gotten more recognition for his work in two films in particular: Stanley Kubrick’s “Paths of Glory” (1957), in which he played a French colonel in World War I trying vainly to prevent the execution of three innocent soldiers, and “Lonely Are the Brave” (1962), an offbeat western about an aging cowboy. He was born Issur Danielovitch on Dec. 9, 1916, in Amsterdam, N.Y., a small city about 35 miles northwest of Albany. Mr. Douglas once estimated that he had held down at least 40 different jobs — among them delivering newspapers and washing dishes — before he found success in Hollywood. After graduating from high school, he hitchhiked north to St. Lawrence University in Canton, N.Y., and was admitted and given a college loan. It was at the Tamarack Playhouse, the summer after he graduated from college, that he decided to change his name legally to something he thought more befitting an actor than Isadore Demsky. Returning to New York, he studied acting for two years, played in summer stock and made his Broadway debut in 1941 as a singing Western Union messenger in “Spring Again.” The next year he enlisted in the Navy and was trained in antisubmarine warfare. He also renewed his friendship with Diana Dill, a young actress he had met at the American Academy. They married in 1943, just before he shipped out during World War II as the communications officer of Patrol Craft 1139. They had two sons, Michael and Joel, before divorcing in 1951. She died in 2015. In 1954 Mr. Douglas married Anne Buydens, and they too had two sons, Peter and Eric. All his sons went into the film business, either acting or producing. Michael did both. Eric Douglas died of an accidental overdose of alcohol and prescription pills in 2004 at the age of 46. In addition to his son Michael, Mr. Douglas is survived by his wife and his two other sons, as well as five grandchildren and a great-grandchild. In 1986 Mr. Douglas was fitted with a pacemaker to correct an irregular heartbeat. In 1991 he survived a helicopter crash that left two other people dead. In January 1996 he suffered a debilitating stroke that left him with seriously impaired speech and depression so deep, he later said, that he considered suicide. In 2015, on his 99th birthday, he and his wife donated $15 million to the Motion Picture & Television Fund in Woodland Hills toward the construction of the Kirk Douglas Care Pavilion, a $35 million facility for the care of people in the industry with Alzheimer’s disease.
