David Bruce Cassidy (April 12, 1950 – November 21, 2017) was an American actor and musician. While he was best known in the United States for his role as Keith Partridge in the 1970s musical-sitcom The Partridge Family, he was an international success in his solo career as a singer. For a period, he was the highest paid entertainer in the world, played sold-out concerts, and had a larger fanbase than Elvis Presley had. Wikipedia
