Claim: Erich von Holst(28 November 1908 – 26 May 1962) was a German behavioral physiologist and founder of the Max Planck Institute for Behavioral Physiology at Seewiesen, Bavaria.from Riga, Livonia who was remembered for his work concerning the processes of endogenous generation of stimuli and of central coordination as a basis of behavioral physiology which refuted the existing "reflex theory".
Evidence: Erich Walther von Holst (28 November 1908 – 26 May 1962) was a German behavioral physiologist who was a Baltic German native of Riga, Livonia and was related to historian Hermann Eduard von Holst (1841–1904). In the 1950s he founded the Max Planck Institute for Behavioral Physiology at Seewiesen, Bavaria. Holst is remembered for his work with zoologist Konrad Lorenz (1903–1989) concerning the processes of endogenous generation of stimuli and of central coordination as a basis of behavioral physiology. This idea refuted the existing "reflex theory" which stated that this behavior was based on a chain of reflexes.
