Franck enjoyed talking about his problems, not so much to explain them to others as to satisfy his own mind. Once a problem had aroused his interest he was completely captivated, indeed obsessed by it. Common sense and straight logic were his main tools, together with simple apparatus. His research followed an almost straight line, from his early studies of ion mobilities to his last work on photosynthesis; it was always the energy exchange between atoms or molecules that fascinated him. 
In addition to the Nobel Prize. Franck was awarded the Max Planck medal of the Deutsche Physikalische Gesellschaft in 1951 and the Rumford Medal of the American Academy of Arts and Sciences for his work on photosynthesis in 1955. He became an honorary citizen of Göttingen in 1953, and was elected a Foreign Member of the Royal Society (ForMemRS) in 1964.He died suddenly from a heart attack while visiting Göttingen on 21 May 1964, and was buried in Chicago with his first wife.In 1967, the University of Chicago named the James Franck Institute after him. A lunar crater has also been named in his honour. His papers are in the University of Chicago Library.
