John R. Buckmaster

John Rodney Buckmaster (18 July 1915 – 1 April 1983) was an English actor on the stage, in films and on television, and a cabaret singer-songwriter. He was the son of actress Dame Gladys Cooper (1888–1971) and Captain Herbert Buckmaster (1881–1966). Educated at Elstree and Eton, he followed his mother into the acting profession and worked on both sides of the Atlantic.

During World War II, he served for a time as a private in the United States Army Air Forces before resuming his acting career until the mid-1950s. He suffered increasingly from mental illness, which led to his confinement at the Priory Hospital, where he died by suicide on 1 April 1983.
