Born David Robert Jones on Jan. 8, 1947, in South London, Mr. Bowie was a person of relentless reinvention. He emerged in the late 1960s with the voice of a rock belter but with the sensibility of a cabaret singer, steeped in the dynamics of stage musicals. He was Major Tom, the lost astronaut in his career-making 1969 hit “Space Oddity.” He was Ziggy Stardust, the otherworldly pop star at the center of his 1972 album “The Rise and Fall of Ziggy Stardust and the Spiders From Mars.” He was the self-destructive Thin White Duke and the minimalist but heartfelt voice of the three albums he recorded in Berlin in the ’70s, often considered his greatest work: “Low,” “ ‘Heroes’ ” and “Lodger.” Mr. Bowie was married for more than 20 years to the international model Iman, with whom he had a daughter, Alexandria Jones. the musician’s son from an earlier marriage, Duncan Jones, said: “Very sorry and sad to say it’s true. I’ll be offline for a while. Love to all.”
