John C. Slater

Who was John C. Slater?

John Clarke Slater was a noted American physicist who made major contributions to the theory of the electronic structure of atoms, molecules and solids. This work is of ongoing importance in chemistry, as well as in many areas of physics. He also made major contributions to microwave electronics. He received a B.S. from the University of Rochester in 1920 and a Ph.D. in Physics from Harvard in 1923, then did post-doctoral work at the universities of Cambridge and Copenhagen. On his return to the U.S. he joined the Physics Department at Harvard.

In 1930, Karl Compton, the President of MIT, appointed Slater as Chairman of the MIT Department of Physics. He recast the undergraduate physics curriculum, wrote 14 books between 1933 and 1968, and built a department of major international prestige. During World War II, his work on microwave transmission, done partly at the Bell Laboratories and in association with the MIT Radiation Laboratory, was of major importance in the development of radar.

In 1950, Slater founded the Solid State and Molecular Theory Group within the Physics Department.
