Felix Kersten (30 September 1898 Yuryev (Dorpat), Imperial Russia – 16 April 1960, Stockholm, Sweden) was before and during World War II the personal masseur of Heinrich Himmler. Kersten used his position to aid people persecuted by Nazi Germany, although whether his actions were as decisive as Kersten claimed in his memoirs is not readily verifiable from other sources.
Kersten began his studies in Helsinki where he studied with the specialist Dr Colander. After two years' study he was awarded his degree in scientific massage. He then left for Berlin where he continued his studies and eventually became Dr. Ko's pupil after an encounter at a dinner party. In 1925 Dr. Ko told Kersten "You have learned all I can teach you." He then turned his patients over to Kersten and retired.
