Franz Tangl

He next was provided with a one-year traineeship for general hospitals and medical institutions, and spent half a year in 1887 in Kiel, dealing primarily with histology.

On April 1 of the same year, he received a post as an assistant in histology in the medical school's embryology division at Graz.

University of Tübingen's Professor Walter Flemming offered him a position as a lecturer, but he returned home due to homesickness in 1891.

Tangl's insistence that physiology be based on sound knowledge of physical chemistry furthered Polanyi's interest in that area.

While there, he contributed significant research into the study of the development, bird embryo, energy and the metabolism of insects during metamorphosis.
