Margret Else Schleidt (born Margret Else Zimmer on July 20, 1928, in Duisburg, died March 13, 2012, in Andechs) was a German human ethologist. She worked at the Max-Planck-Institut für Verhaltensphysiologie, which has now become the Max-Planck Institute for Ornithology.
Margret Else Schleidt studied Biology at the Universities of Bonn, Zurich and Freiburg. She did her dissertation[1] research in animal ethology at Konrad Lorenz’s research station in Buldern Westfalen. She then completed her PhD in animal ethology in 1955 under the supervision of Professor Otto Koehler in Freiburg i Br., before working as part of Konrad Lorenz’ research group at the Max-Planck-Institut für Verhaltensphysiologie in Seewiesen. At that time, she worked with Wolfgang Schleidt on ornithological projects. From 1963 to 1974, Margret Schleidt was secretary to the Lorenz group.
In 1974, she joined of the Human Ethology group led by Irenäus Eibl-Eibesfeldt in Seewiesen. Her research focus was on human communication. She wrote papers on the importance of olfaction, mother-child relationships, and rhythmic movement phenomena. Importantly, she discovered that various repeated behaviours such as stirring while cooking, scratching, and other non-repeated behaviours had a three-second rhythm, in different human cultures, as well as in chimpanzees and baboons. In addition, she advised students writing their dissertations.
