Nora Maier was born on Nov. 6, 1942, in Munich. After the war, her father, Franz Karl Maier, was a prosecutor who helped bring wartime Nazis to justice. He was later the editor and publisher of the newspaper Tagesspiegel.
Ms. Forster went on to work as a model and to marry the singer Frank Forster, who was “kind of a swing pop star, always appearing on TV back in the ’60s,” Arianna Forster said in an interview with the music site Pitchfork in 2009, a year before she died.
Nora Forster’s survivors include her husband and three grandchildren.
As the 1960s unfolded, Ms. Forster promoted West German tours for acts like Jimi Hendrix and Yes, which gave her prominence on the German rock scene. “People were walking around in the living room back then, like the Bee Gees and all these big groups,” her daughter recalled in the Pitchfork interview.
The bohemian lifestyle of her rock friends eventually ran afoul of the local authorities. “In Munich, the police were knocking at the door every night because of the loud acid parties,” her daughter once said. “She was fed up with it. You have to go to London to live that lifestyle.”
Ms. Forster did just that in about 1970, and by the middle of the decade she had become enmeshed in the punk-rock scene that was starting to roil Britain and the music industry as a whole. She became “a den mother to all the young punks,” said Arianna, who in 1976, at age 14, would rename herself Ari Up and join with a drummer called Palmolive to found the Slits, which became a leading female punk band of the era.
In 1975, Ms. Forster met Mr. Lydon, who was nearly 14 years her junior, at Sex, the boundary-pushing clothing boutique on London’s King’s Road run by the fashion designer Vivienne Westwood and the Sex Pistols’ manager, Malcolm McLaren.
