Richard St. John Harris (1 October 1930 – 25 October 2002) was a two-time Academy Award-nominated and Grammy Award-winning Irish actor, singer-songwriter, theatrical producer, film director and writer. He appeared on stage and in many films, and is perhaps best known for his roles as King Arthur in Camelot (1967), as Oliver Cromwell in Cromwell (1970) and for his portrayal of Albus Dumbledore in Harry Potter and the Philosopher's Stone (2001) and Harry Potter and the Chamber of Secrets (2002), his last film. He also played a British aristocrat and prisoner in A Man Called Horse (1970), a gunfighter in the Clint Eastwood directed western Unforgiven (1992), and emperor Marcus Aurelius in Gladiator (2000).
Richard Harris portraits the character of Albus Dumbledore in the first two Harry Potter seasons - Harry Potter and the Philosopher's Stone TV Serie and Harry Potter and the Chamber of Secrets TV Serie.
He also played the role in the first two films.
He was friends with actor Peter O'Toole. After Harris died, his family hoped that O'Toole would replace him as Professor Albus Dumbledore in Harry Potter and the Prisoner of Azkaban (2004) and Harry Potter and the Prisoner of Azkaban TV Serie (2003). He was replaced by fellow Irish-born actor Sir Michael Gambon.
