Penny Marshall, the celebrated director of beloved films like Big and A League of Their Own, has died. She was 75 years old. Marshall died in her Los Angeles, California home on Monday night from problems linked to diabetes. “Our family is heartbroken,” the Marshall family said in a statement. Marshall first found fame on the television show Laverne & Shirley, which ran from 1976 to 1983. She played Laverne DeFazio, a loud, Bronx-born young adult living in a Midwestern city. Cindy Williams played her friend Shirley. The hit series centered on working-class women, a rarity in television at the time. In her 2012 book, My Mother Was Nuts, Marshall offered her reasoning for the popularity of the show: “I thought it was simply because Laverne and Shirley were poor and there were no poor people on TV, but there were plenty of them sitting at home and watching TV.” Marshall’s older brother, Garry Marshall, was a well-known filmmaker and producer. He created Laverne & Shirley.
