Life

Fritz Lehmann was the son of the Swiss painter and university professor Wilhelm Ludwig Lehmann and the nephew of the hygienist Karl Bernhard Lehmann . He first studied medicine at the University of Zurich , but soon switched to zoology . In addition to his studies, he was assistant to the later Nobel Prize winner Walter Rudolf Hess . In 1925 he was at Karl Hescheler with a thesis on the tracheal system of the Indian stick insects doctorate . He then sat in with Hans Spemann in Freiburg, Ross Granville Harrison at Yale University and John Runnström in Stockholm. After these stays, Lehmann devoted himself to developmental physiology .

From 1929 Lehmann worked as an assistant to Fritz Baltzer at the University of Bern , where he completed his habilitation in 1931 . A research stay took him to the Carlsberg Laboratory in Copenhagen. After the extraordinary professorship since 1940, he was appointed full professor in 1949. From 1954 to 1965 Lehmann was Baltzer's successor, head of the Zoological Institute in Bern. Due to a serious illness, he gave up this post before his retirement in 1968.

Lehmann's main research interests included developmental physiology, cell biology and comparative and experimental morphology . He researched the chemical influence of cell division and tissue growth. His working method was that of synthesis. Lehmann's main work, Introduction to Physiological Embryology , received international recognition and was reprinted several times. In 1967 he was chairman of the 8th International Embryologist Congress in Interlaken.

Fritz Lehmann was for many years Vice President of the “International Society of Cell Biology”, a founding member of the “Institut International d'Embryologie” and President of the Research Commission of the Swiss Natural Research Society (SNG). In addition to research, Lehmann was very interested in teacher and adult education. He was a member of the board of the Bern Adult Education Center for many years and lectured at schools. Fritz Lehmann was married and had children. The brain anatomist Hugo Spatz was his cousin.
