'One Day at a Time' Star Bonnie Franklin Dead at 69
Bonnie Franklin, best known for her role as a single mom on the '70s-'80s sitcom "One Day at a Time," died at her Los Angeles home this morning of complications from pancreatic cancer. She was 69 years old, and died surrounded by her family, confirmed her agent, Robert Malcolm. The cancer was diagnosed in August, and the actress revealed shortly after that she was undergoing treatment. On "One Day at a Time," which was developed by Norman Lear and aired from 1975 to 1984, Franklin was groundbreaking as Ann Romano, the single mother of two daughters, who were played by Valerie Bertinelli and Mackenzie Phillips. The show was an anthem for a generation grappling with difficult issues never portrayed before on a sitcom. When the show was in its prime, millions tuned in to watch what was regarded as TV's first realistic portrayal of a divorced mother struggling to raise her teenage daughters.
