Henry Hamilton Beamish (2 June 1873 – 27 March 1948) was a leading British antisemite and the founder of The Britons in 1919 which soon for some decades focussed on its publishing arm, of which he was president.
From the age of 46 he was a touring speaker, claimed to have taught Adolf Hitler and was on the payroll of Nazi Germany across North America, with emphasis on Canada.
From 1938 he lived in South Rhodesia where he spent two years as an independent politician, saw wartime internment and died short of three years after the end of World War II aged 74.
