McClintock received a fellowship from the Guggenheim Foundation that made possible six months of training in Germany during 1933 and 1934. She had planned to work with Curt Stern, who had demonstrated crossing-over in Drosophila just weeks after McClintock and Creighton had done so; however, Stern emigrated to the United States. Instead, she worked with geneticist Richard B. Goldschmidt, who was a director of the Kaiser Wilhelm Institute for Biology in Berlin. She left Germany early amidst mounting political tension in Europe, returned to Cornell, but found that the university would not hire a woman professor. In 1936, she accepted an Assistant Professorship offered to her by Lewis Stadler in the Department of Botany at the University of Missouri in Columbia. While still at Cornell, she was supported by a two-year Rockefeller Foundation grant obtained for her through Emerson's efforts.
