William Joyce (1906-1946), often referred to as Lord Haw-Haw, was a Nazi propagandist during World War II. Joyce was born in New York, and moved to England as a teenager. He became a member of the British Union of Fascists, holding a German-sympathetic opinion of the growing tension, in the 1930s. Joyce moved to Germany shortly before the beginning of the war, and immediately began recording radio propaganda that was broadcast for British audiences.
Joyce's last broadcast was on April 30, 1945, which is the same day that Adolf Hitler committed suicide. He was captured in May, and was shot during his capture. The shot was not fatal, but he did not have much longer to live.
Joyce was prosecuted for treason by the United Kingdom, despite the fact that he was not a British citizen. The grounds given for British jurisdiction were that Joyce had nevertheless possessed a British passport and had falsely claimed British citizenship. His wife, Margaret, had broadcast alongside her husband, but was not prosecuted because officials "felt that she had suffered enough", according to secret files that were released in 2000.  William Joyce was found guilty of these charges, and was hanged in January, 1946.
