Polykarp Kusch joins Columbia University as an instructor. Here he works with the physicist Isidor I. Rabi on studies of the effects of magnetic fields on beams of atoms. In 1946 he is appointed Associate Professor of Physics and Full Professor in 1949. He serves as Chairman of Columbia’s physics department from 1949 to 1952. He is also promoted to Academic Vice President and Provost of the entire university from 1969 to 1972.

Polykarp Kusch earns his Ph.D. at the University of Illinois. He researches on optical spectroscopy under the supervision of F. Wheeler Loomis.

Polykarp Kusch receives one half of the Nobel Prize for Physics "for his precision determination of the magnetic moment of the electron," the other half being awarded to Willis E. Lamb "for his discoveries concerning the fine structure of the hydrogen spectrum."

Polykarp Kusch is appointed Professor of Physics and then Eugene McDermott Professor at the University of Texas in Dallas. He retires as Professor Emeritus in 1982.

Polykarp Kusch enters the Case School of Applied Science (later named Case Western Reserve University) initially to study chemistry and chemical engineering but his interest rapidly shifts to physics. Kusch designs most of the scientific apparatus used for his experiments in those days. He graduates with a Bachelor of Science degree with a major in physics in 1931.

Polykarp Kusch dies in Dallas at the age of 82.

Polykarp Kusch with the help of Henry M. Foley measures the magnetic moment of the electron. This is found to be larger by about one part in 1,000 from the value calculated by Paul Dirac. This work has a profound impact on the development of quantum electrodynamics.

Polykarp Kusch is engaged in research on the military applications of microwave generators at the Westinghouse Electric Corporation. He returns then from 1942 to 1944 at Columbia University.

Polykarp Kusch spends these years in research and development on improved radio frequency generators of variable high or microwave frequencies at Bell Telephone Laboratories.

Polykarp Kusch and his family relocate in the United States. They move to various locations in the Midwest before settling in Cleveland, where Kusch attends public schools and becomes a naturalized American citizen in 1922.

Polykarp Kusch joins the University of Minnesota as Research Assistant. Here he specialises in mass spectroscopy under Professor John T. Tate.

Polykarp Kusch is born in Blankenburg, the son of John Mathias Kusch, a Lutheran clergyman and Henrietta van der Haas, a novelist.

Polykarp Kusch earns his M.S. at the University of Illinois.
