Tamara Dembo's European years: working with Lewin and Buytendijk

In this paper early work of the American rehabilitation psychologist Tamara Dembo (1902-1993) is brought to light. She was highly influenced by the concepts of Kurt Lewin's topological psychology, and she used the framework of topological psychology to analyze her investigations on animal behavior carried out with the Dutch zoopsychologist Frederik J. J. Buytendijk. These investigations have so far been ignored and are being described for the first time making use of archival materials.
