Sir Alan Arthur Bates CBE (February 17, 1934 – December 27, 2003) was a British bisexual actor.
Bates was married to the actress Victoria Ward from 1970 until her death in 1992. The Bateses had twin sons born in 1971, the actors Benedick Bates and Tristan Bates. Tristan died suddenly in 1990 during an asthma attack. The Bateses are also survived by granddaughter, Chatto Bates, Benedick's daughter.
In the later years of his life, Alan Bates's companion was his lifelong friend, actress Joanna Pettet, his co-star in the 1964 Broadway play Poor Richard. They divided their time between New York and London.
In May 2007 several articles were published with people from Bates's past with assertions that he had engaged in longtime relationships with men, including ten years relationship with fellow actor Peter Wyngarde, five years relationship with Gerard Hastings and two years relationship with Olympic skater John Curry.
Bates died of pancreatic cancer in 2003.
