Koffka left Frankfurt in 1912 to take a position at the University of Giessen, where he worked for over eleven years. Koffka then travelled to the United States, where he was a visiting professor at Cornell University from 1924 to 1925, and two years later at University of Wisconsin–Madison. Eventually, in 1927, he accepted a position at Smith College in Northampton, Massachusetts, where he remained until his death in 1941.
