Walter Kohn

Walter Kohn was a renowned Austrian-American theoretical physicist and chemist who made significant contributions to the field of density functional theory, working alongside notable scientists such as John Slater, Edward Teller, and Robert Mulliken. His work had a profound impact on the development of modern physics and chemistry, influencing researchers at institutions like Stanford University, Massachusetts Institute of Technology, and University of Cambridge. Kohn's collaborations with Nobel laureates like Pierre-Gilles de Gennes and Philip Anderson further solidified his position in the scientific community. His research was often published in esteemed journals such as Physical Review and Journal of Chemical Physics, which are affiliated with organizations like American Physical Society and American Chemical Society.

● Early Life and Education

Walter Kohn was born in Vienna, Austria, to a family of Jewish descent, and his early life was marked by the influence of prominent figures like Sigmund Freud and Ludwig Wittgenstein. He attended the Akademisches Gymnasium in Vienna before fleeing to England in 1939 to escape the Nazi occupation. Kohn then moved to Canada, where he attended University of Toronto and later earned his undergraduate degree from University of Toronto in 1945. He went on to pursue his graduate studies at Harvard University, working under the supervision of Julian Schwinger, a prominent physicist who was also a Nobel laureate. Kohn's time at Harvard University was marked by interactions with other notable scientists, including Richard Feynman and Hans Bethe, who were affiliated with institutions like California Institute of Technology and Cornell University.

● Career

Kohn began his academic career as a research fellow at Harvard University and later became a lecturer at Carnegie Institute of Technology, which is now known as Carnegie Mellon University. In 1950, he joined the faculty at University of Pittsburgh, where he worked alongside Frederick Seitz, a renowned physicist and National Medal of Science recipient. Kohn's subsequent appointments included positions at University of California, San Diego, University of California, Berkeley, and University of California, Santa Barbara, where he collaborated with scientists like David Gross and Frank Wilczek, both Nobel laureates in Physics. His research was often supported by organizations like National Science Foundation and Department of Energy, which also funded projects at institutions like Princeton University and University of Chicago.

● Research and Contributions

Walter Kohn's most notable contribution to science was the development of density functional theory, a computational method used to study the behavior of electrons in atoms and molecules. This work, which was influenced by the research of Lev Landau and Evgeny Lifshitz, has had a significant impact on the field of condensed matter physics and has been applied to a wide range of systems, including metals, semiconductors, and superconductors. Kohn's research also explored the properties of ferromagnetism and antiferromagnetism, topics that were also studied by scientists like Louis Néel and Pierre-Ernest Weiss. His work was often published in collaboration with researchers from institutions like University of Oxford, University of California, Los Angeles, and Georgia Institute of Technology.

● Awards and Honors

Throughout his career, Walter Kohn received numerous awards and honors for his contributions to science, including the Nobel Prize in Chemistry in 1998, which he shared with John Pople. He was also awarded the National Medal of Science in 1988 and was elected a member of the National Academy of Sciences and the American Academy of Arts and Sciences. Kohn received honorary degrees from institutions like University of Vienna, Hebrew University of Jerusalem, and Technion – Israel Institute of Technology, and was a fellow of the American Physical Society and the American Chemical Society. His work was recognized by organizations like Royal Society, French Academy of Sciences, and Russian Academy of Sciences, which also honored scientists like Andrei Sakharov and Pyotr Kapitsa.

● Personal Life

Walter Kohn was married to Mara Vorhausen and had two daughters, Monica Kohn and Ingrid Kohn. He was an avid hiker and mountain climber and enjoyed spending time outdoors in places like Sierra Nevada and Rocky Mountains. Kohn was also a talented pianist and enjoyed playing the music of Ludwig van Beethoven and Johannes Brahms. He passed away on April 19, 2016, at the age of 93, leaving behind a legacy of scientific contributions and a community of researchers who continue to build upon his work at institutions like Stanford University, Massachusetts Institute of Technology, and University of Cambridge.
