Overview
David Bruce Cassidy (April 12, 1950 – November 21, 2017) was an American actor and musician. He was best known for his role as Keith Partridge, the son of Shirley Partridge (played by his real-life stepmother, actress Shirley Jones), in the 1970s musical-sitcom The Partridge Family. This role catapulted Cassidy to teen idol status as a superstar pop singer of the 1970s.
Early life
Cassidy was born at Flower Fifth Avenue Hospital in New York City, the son of singer and actor Jack Cassidy and actress Evelyn Ward. His father was of half Irish and half German ancestry, and his mother was descended mostly from Colonial Americans, along with having some Irish and Swiss roots. His mother's ancestors were among the founders of Newark, New Jersey.
As his parents were frequently touring on the road, he spent his early years being raised by his maternal grandparents in a middle-class neighborhood in West Orange, New Jersey. In 1956, he found out from neighbors' children that his parents had been divorced for over two years and had not told him.
In 1956, Cassidy's father married singer and actress Shirley Jones. They had three children, David's half-brothers Shaun (b. 1958), Patrick (b. 1962), and Ryan (b. 1966). In 1968, after completing one final session of summer school to obtain credits necessary to get a high school diploma, David moved into the rental home of Jack Cassidy and Shirley Jones in Irvington, New York, where his half-brothers also lived. David remained there, seeking fame as an actor/musician, while simultaneously working half-days in the mailroom of a textile firm. He moved out when his career began to flourish.
