Hedwig Kohn was among one of the physicists, who was forced to leave Germany during the Nazi regime.

Hedwig Kohn was born in Breslau, Province of Silesia. Hedwig father Georg Kohn was a wholesale merchant of fine cloth. Hedwig entered the university in Breslau in 1907 as the second woman in the physics department and later she obtained her doctorate in physics under Otto Lummer in 1913 and was soon appointed as Lummer's assistant. She stayed at the university's Physics Institute during World War I and obtained her Habilitation in 1930.

Hedwig Kohn under Lummer guidance in the quantitative determination of the intensity of light, both from broad-band sources, such as a "black body", and from the discrete emission lines of atoms and molecules. She wrote 270 pages in the leading physics text of the 1930s and 1940s in Germany, received one patent, and wrote numerous articles in scientific journals, some of which were still being cited into the 1980s.
