antisemitism may have been a usually unspoken factor. Offered temporary positions at three women's colleges in the United States through the aid of Rudolf Ladenburg, Lise Meitner, Hertha Sponer, the American Association of University Women, and many others, Kohn left Germany. She had been given a visa to the United Kingdom in 1939, but it was cancelled because of World War II; she eventually secured a visa to travel to Sweden and immediately went there in July 1940. On receiving a visa from the United States, she then moved there. The journey to her first position at the Women's College of the University of North Carolina in Greensboro took Kohn through Berlin, Stockholm, Leningrad, Moscow, Vladivostok, Yokohama, San Francisco, and Chicago. Life in United States When Kohn arrived in the United States in January 1941, she was seriously ill. After recovering, Kohn taught at the Women's College of the University of North Carolina at Greensboro for a year and a half. In 1942, she began teaching at Wellesley College in Massachusetts. She started as a lecturer, became an associate professor in 1945, and then was awarded full professorship in 1948. Kohn established a research laboratory for flame spectroscopy while at the college. She was a member of a number of professional associations in the United States, including the American Physical Society, the American Association of Physics Teachers, and Sigma Xi: The Scientific Research Honor Society. Upon Kohn's retirement as professor in 1952, Hertha Sponer, then professor of physics at Duke University in Durham, North Carolina, offered her a position as a research associate. Kohn set up a laboratory at Duke University and resumed research, where she guided two graduate students to their doctorates and recruited two post-doctoral fellows to assist in her study of flame spectroscopy. She worked there until very shortly before her death in 1964. Legacy Kohn was trained by Otto Lummer 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 further developed such methods and devised ways of extracting information from intensity measurements and from emission line shapes. 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 2000s. Kohn also published
