Lauren Chapin, the youngest kid on Father Knows Best, has died after a five-year battle with cancer. She was 80.

The late actress, who was born in Los Angeles, California in 1945, got her start in acting as a child in the 1950s, with an appearance on a 1952 episode of CBS' Lux Video Theatre, followed by one on 1954's A Star Is Born starring Judy Garland. 

She was cast in the Robert Young-led sitcom, which ran from 1954 to 1960, when she was nine years old, starring as Jim Anderson's youngest daughter Kathy Anderson, appearing in 196 of the sitcom's 203 episodes, for which she was awarded five Junior Emmys for Best Child Actress.

The years after Father Knows Best ended were difficult for Lauren, but she eventually got sober in 1970, and took on a variety of jobs. Learn about her below.
