Walter Kohn (born March 9, 1923 in Vienna, Austria) is an Austrian-born American theoretical physicist who was awarded, with John A. Pople, the Nobel Prize in chemistry in 1998. The award recognized their contributions to the understandings of the electronic properties of materials. In particular, Kohn played a leading role in the development of the density functional theory, which made it possible to incorporate quantum mechanical effects in the electronic density (rather than through its many-body wavefunction). This computational simplification led to many insights and became an essential tool for electronic materials, atomic and molecular structure.

Kohn was awarded his B.A. degree in mathematics and physics by the University of Toronto in 1945; he was awarded an M.A. degree in applied mathematics by Toronto in 1946. Kohn was awarded a Ph.D. degree in physics by Harvard University in 1948. He was a professor at Carnegie Mellon University from 1950-1960, where he did much of his seminal work on semiconductor physics. He moved to the newly founded University of California at San Diego in 1960, where he remained until 1979. He then accepted the Founding Director's position at the new Institute for Theoretical Physics in Santa Barbara.
