David Bruce Cassidy was an American actor, singer, songwriter and guitarist. He was known for his role as Keith Partridge in the 1970s musical-sitcom The Partridge Family. It was within this role that led to him becoming one of popular culture's teen idols and pop singers of the 1970s. Ten albums by The Partridge Family and five solo albums were produced during the series, with most selling more than a million copies each. Internationally, Cassidy's solo career eclipsed the already phenomenal success of The Partridge Family. He became an instant drawcard, with sellout concert successes in major arenas around the world. These concerts produced mass hysteria, resulting in the media coining the term ‘Cassidymania’. In November 2017 Cassidy was hospitalised, suffering from liver and kidney failure and died on 21 November 2017.
