James Franck was born on August 26, 1882, in Hamburg, Germany. After attending the Wilhelm Gymnasium there, he studied mainly chemistry for a year at the University of Heidelberg , and then studied physics at the University of Berlin, where his principal tutors were Emil Warburg and Paul Drude. He received his Ph.D. at Berlin in 1906 under Warburg, and after a short period as an assistant in Frankfurt-am-Main, he returned to Berlin to become assistant to Heinrich Rubens. In 1911, he obtained the "venia legendi" for physics to lecture at the University of Berlin, and remained there until 1918 (with time out for the war in which he was awarded the Iron Cross, first class) as a member of the physics faculty having achieved the rank of associate professor.

Franck, James James Franck Bavaria-Verlag Nobel Prize for Physics in 1925 with Gustav Hertz for research on the excitation and ionization of atoms by electron bombardment that verified the quantized nature of energy transfer. Franck studied at the universities of Heidelberg and Berlin, received his doctorate from the latter in 1906, and served in the German army during World War I. He and Hertz performed their prizewinning work at the University of Berlin in 1912-14. They bombarded mercury atoms with electrons and traced the energy changes that resulted from the collisions. They found that electrons with insufficient velocity simply bounced off the mercury atoms, but that an electron with a higher velocity lost precisely 4.9 electronvolts of energy to an atom. If the electron had more than 4.9 volts of energy, the mercury atom still absorbed only that amount. The Franck-Hertz experiment gave proof of Niels Bohr's theory that an atom can absorb internal energy only in precise and definite amounts, or quanta. Franck's researches in the fields of photochemistry and atomic physics included determinations from molecular band spectra of the energy involved in the dissociation of molecules. During World War II he worked on the Manhattan Project, which developed the atomic bomb. Franck became a leader of those scientists in the Manhattan Project who sought to stop the bomb's use against Japan; they instead suggested that the bomb be exploded in an unpopulated area to demonstrate its power to the Japanese government.

ABOUT THE INSTITUTE History University of Chicago Research Institutes: 50 years of scientific achievements Oct. 17, 1995 Click here to view photos related to this article. For 50 years, the University of Chicago's Research Institutesthe Enrico Fermi Institute and the James Franck Institutehave fostered an interdisciplinary dialogue between scientists that has resulted in some of the most notable scientific achievements of the 20th century. The EFI and JFI, founded in 1945 as the Institute for Nuclear Studies and the Institute for the Study of Metals, respectively, are two of the oldest academic centers for interdisciplinary research in the world. They were founded by then-Chancellor Robert Hutchins, who recognized the wealth of intellectual talent that had assembled at Chicago to work on the Manhattan Project and conceived of the institutes as a way to retain these world-class scientists at Chicago. Hutchins saw the institutes as a way to continue the dialogue between pure science and technology that had been initiated during the Manhattan Project, as well as a way to ease the barriers between traditional scientific disciplines. The mobilization of scientists and engineers to solve wartime problems had revealed the extraordinary advantages of bringing together scientists from different backgrounds to focus on problems of national interest. Interdisciplinary research has since come to be considered crucial to scientific progress, but at no other university was such a commitment made so early and so thoroughly.

ABOUT THE INSTITUTE News of the JFI Physicist Ugo Fano dies at 88 March 15, 2001 Ugo Fano, Professor Emeritus in Physics and the James Franck Institute, whose pioneering contributions to the theory of atomic and radiation physics helped lead to the development of the gas laser and the use of radiation in medical diagnosis and therapy, died Tuesday, Feb. 13, in Chicago. He was 88. Inokuti noted that Fano began his career working with Enrico Fermi at the University of Rome from 1934 to 1936. Fermi, a 1938 Nobel laureate in physics, led a group of scientists at the University to produce the first controlled, self-sustaining nuclear chain reaction in 1942. Fano came to the University in 1966 as a Professor in Physics and the James Franck Institute. He served as Chairman of the Physics Department from 1972 to 1974. He produced approximately 30 Ph.D. students, most of who currently serve as faculty members active in the field of atomic physics. Fano was born in Torino, Italy, on July 28, 1912. He earned his doctoral degree in mathematics from the University of Torino in 1934, then began working with Enrico Fermi. Fano returned to the University of Rome as a lecturer in 1938, but fled with his family to the United States in 1939 to escape fascist Italy. He worked at the Washington Biophysical Institute, the Carnegie Institution of Washington and the U.S. Army Ballistic Research Laboratory from 1939 to 1945, and at the National Bureau of Standards from 1946 to 1966.

Franck, James German-born US physicist. He shared a Nobel prize 1925 with his co-worker Gustav Hertz (1887-1975) for their experiments of 1914 on the energy transferred by colliding electrons to mercury atoms, showing that the transfer was governed by the rules of quantum theory. Investigating the collisions of electrons with rare-gas atoms, Franck found that they are almost completely elastic and that no kinetic energy is lost. With Hertz, he extended this work to other atoms. This led to the discovery that there are inelastic collisions in which energy is transferred in definite amounts. Franck also studied the formation, dissociation, vibration, and rotation of molecules, and was able to calculate the dissociation energies of molecules. Edward Condon (1902-1974) interpreted this method in terms of wave mechanics, and it has become known as the Franck-Condon principle.
