John Henry Clarke

John Henry Clarke (1853 – 24 November 1931) was an English classical homeopath. He was also, arguably, the highest profile anti-Semite of his era in Great Britain. He led The Britons, an anti-Semitic organisation. Educated at the University of Edinburgh, he received his medical degree in 1877.

As a physician Clarke had his own clinic in Piccadilly, London, but he also was a consultant at the London Homeopathic Hospital and did research into new homeopathic remedies.

Politics
Clarke was a leading advocate of anti-Semitism and served as president of The Britons, as an associate of Henry Hamilton Beamish, from its formation in 1919 until his death. He wrote several articles on Christianity that have a militant bent. When Beamish became a fugitive and fled England, Clarke became the head of The Britons, and formed with two others a splinter organization, the Britons Publishing Society.

Works
For many years, he was the editor of The Homeopathic World. He wrote many books, his best known were Dictionary of Practical Materia Medica and Repertory of Materia Medica (i.e., the Clinical Repertory), both of which are recommended by the U.S. Food and Drug Administration's rules on "Conditions under Which Homeopathic Drugs May be Marketed".
