Life

Fritz Kirchner was born on November 1, 1896, the son of Christian Kirchner and his wife Ida. After studying physics, he did his doctorate in 1921 at Max Wien in Jena on the subject of structural studies with X-rays . He then lived in Munich from 1921 to 1934, where he taught as a private lecturer from 1925. In the same year he married the doctor Susanne Margareta Börner with whom he had four sons and a daughter.

After Kirchner was assistant to Wilhelm Wien for some time , he completed his habilitation in 1927. Two years later, in 1929, Kirchner became an assistant to Arnold Sommerfeld before he was given a teaching position in theoretical physics in 1930. A year later he was appointed associate professor at the University of Munich . Soon afterwards he became a full professor for applied physics and experimental physics as well as director of the Physics Institute at the University of Cologne .

Kirchner, a member of the NSDAP since 1940 , was involved in research into technical energy generation for the Army Weapons Office during World War II . After the end of the war, he was banned from teaching until 1947. He then taught again at Cologne University.
