Jörg-Peter Ewert (born 1938 in the Free City of Danzig) is a German neurophysiologist and researcher in the field of Neuroethology. From 1973 to 2006, he served as a university professor (Chair of Zoology/Physiology) in the Faculty of Natural Sciences at the University of Kassel, Germany.
From 1958 to 1965 Jörg-Peter Ewert studied the specialties biology, chemistry, and geography at the University of Göttingen. He graduated in 1965 and took up the specialty of zoology under the direction of the behavior physiologist Georg Birukow. The subject of Ewert’s PhD (Dr.rer.nat.) dissertation was: "The influence of peripheral sensory and central nervous system responses on the readiness of the orienting movement in the common toad". Later he passed the state examination for the lecturing at secondary schools.
After 1966, he was a scientific assistant at the zoological institute of the Darmstadt University of Technology at Darmstadt. First he worked under the developmental physiologist Wolfgang Luther and continued under the sense physiologist Hubert Markl. In 1968 he received an invitation from the neurophysiologist Otto-Joachim Grüsser offering him a research visit for neuron recordings at the physiological institute of the Free University of Berlin. He used the methodological knowledge acquired to begin recording neurons from the visual system of the common toad.
In 1969 he obtained his Habilitation degree, the Venia Legendi for Zoology (focus on Physiology), at the Darmstadt University of Technology.
During a research project 1970-71, he worked as a Fellow of the Foundations' Fund for Research in Psychiatry with the neuropsychologist David J. Ingle at the McLean Hospital (Harvard Medical School) in Belmont, MA, USA.
From 1971-1972 he worked as a university professor at the zoological institute of the Darmstadt University of Technology.
