David Bruce Cassidy (April 12, 1950 – November 21, 2017) was an American actor, singer, songwriter, and guitarist. He was known for his role as Keith Partridge, the son of Shirley Partridge (played by his stepmother Shirley Jones), in the 1970s musical-sitcom The Partridge Family, which led to his becoming one of popular culture’s teen idols and pop singers of the 1970s. He later had a career in both acting and music.
In 1970, Cassidy took the role of Keith Partridge, son of Shirley Partridge, who was played by Cassidy’s real stepmother and series lead Shirley Jones. The Partridge Family series creator Bernard Slade and producers Paul Junger Witt and Bob Claver did not care whether Cassidy could sing, knowing only that his androgynous good looks would guarantee success. Shortly after production began, though, Cassidy convinced music producer Wes Farrell that he was good enough, and he was promoted to lead singer for the series’ recordings.
Once “I Think I Love You” became a hit, Cassidy began work on solo albums, as well. Within the first year, he had produced his own single, “Cherish” (from the album of the same title), which reached number nine in the United States, number two in the United Kingdom, and number one in Australia and New Zealand. He began tours that featured Partridge tunes and his own hits. Though he wanted to become a respected rock musician along the lines of Mick Jagger, his channel to stardom launched him into the ranks of teen idol, a brand he loathed until much later in life, when he managed to come to terms with his bubblegum pop beginnings
