Otto Frank (21 June 1865 – 12 November 1944) was a German born doctor and physiologist who made several important contributions to cardiac physiology and cardiology. The Frank-Starling law of the heart is named after him and Ernest Starling.
(Friedrich, Wilhelm, Ferdinand) Otto Frank was born in Groß-Umstadt and was the son of Georg Frank (1838–1907), a doctor of medicine and a practicing physician, and Mathilde Lindenborn (1841–1906). Otto Frank was married to Theres Schuster in a Catholic wedding in München .
Otto Frank studied medicine in München and Kiel between 1884 and 1889 (approbation in München 1889). During 1889 to 1891 he undertook training in mathematics, chemistry, physics, anatomy and zoology in Heidelberg, Glasgow, München and Straßburg. He then worked until 1894 as an assistant to Carl Friedrich Wilhelm Ludwig in the Physiologisches Institut in Leipzig. There in 1892 he completed his doctoral studies (Promotion).
Subsequently, from 1894 Frank worked as an assistant in Carl von Voit's Physiological Institute in München where he studied cardiac function using approaches derived from earlier thermodynamic analyses of skeletal muscle contraction. His work on the behaviour of heart muscle was the topic of his post doctoral work. In 1902 he became an Extraordinary Professor and from 1905 to 1908 he undertook further work on this topic before becoming a full professor (Ordinariat). Then he returned to München to continue this work. Carl J. Wiggers visited Frank’s laboratory in 1912 and found Frank a ‘‘brilliant analyst, a skillful systematist, a talented mathematician, and a creative thinker...’’, but secretive and difficult to work with. Wiggers returned to the US in the fall of 1912 having ‘smuggled’ copies of some of Frank’s equipment out with him, despite this Wiggers and Frank seem to have maintained cordial relations subsequently. Frank appears to have been a demanding teacher and Richard Bing, an Editor of the Journal of Molecular and Cellular Cardiology, who studied with Frank, recalled him as '...a holy terror, hating mediocrity, and many a student bit the dust in the examination in Physiology'. Frank continued to work in München until his enforced retirement in 1934 due to his opposition to the Nazi regime.
