Paul Bargehr (18 March 1889 – 31 December 1951) was an Austrian medical doctor and writer mostly known for his work treating Hansen's disease (leprosy) in the Dutch East Indies (now Indonesia). Although the Japanese researcher Kensuke Mitsuda receives credit for first developing the modern lepromin test for distinguishing between different forms of Hansen's disease, Bargehr's work was responsible for coining and popularizing its current name.
