William Joyce (24 April 1906 - 3 January 1946), known as Lord Haw-Haw from his vocal tic, was an American-born fascist politician and Nazi propaganda broadcaster to the United Kingdom during World War II. He was executed for treason after the war by the British government. Technically, this charge was false, as he was never a British national.
Not long after the Second World War broke out in October, 1938, William Joyce went to Germany and began broadcasting under the guise of Lord Haw-Haw on behalf of the Nazis. After the "big switch" of 1940, Joyce began broadcasting variations on the theme of I told you so. In 1943, after the British and French turned on Germany once more and after a series of uprisings especially in Münster, Joyce continued to broadcast in support of the Nazis stating that the German people remained united behind Hitler.
