John Walter Clark, PhD, Wayman Crow Professor of Physics Emeritus at Washington University in St. Louis, has been recognized by Marquis Who’s Who Top Educators for dedication, achievements, and leadership in physics and higher education.

Interested in becoming a scientist since he was four years old, Dr. Clark has always been interested in science, astronomy and science fiction books. Receiving a Bachelor of Science and Master of Arts from the University of Texas at Austin in 1955 and 1957, respectively, he subsequently attended Washington University in St. Louis, where he earned a Doctor of Philosophy in 1959. A National Science Foundation postdoctoral fellow at Princeton University for the following two years, he first served as an associate research scientist for The Martin Company in Denver, CO, in 1961 and a NATO postdoctoral fellow at the University of Birmingham in England in 1962. From 1962 to 1963, he was also a NATO postdoctoral fellow at the Centre D’études Nucléaires de Saclay in Saclay, France, and soon transitioned to an assistant and associate professor of physics at Washington University in St. Louis in 1963.

Dr. Clark remained at Washington University in St. Louis for the remainder of his career, serving as a professor of physics from 1972 to 1999 and a Wayman Crow Professor of Physics from 1999 until attaining emeritus status in 2016. During this time, he was also the chairman of the department of physics from 1996 to 1997 and again from 2002 to 2007. Alongside his primary endeavors, Dr. Clark has been a scientist-in-residence at the Center for Mathematical Sciences and CIMA at the University of Madeira in Portugal since 2014, an associate of the European Centre for Theoretical Studies in Nuclear Physics and Related Areas in Trento, Italy, since 1998, and a member of the international advisory board for the Institute for Advanced Studies in Basic Sciences in Zanjan, Iran, since 1996. Likewise, he has also been a member of the Eugene Feenberg Medal selection committee since 1987, chair and honorary president of the international advisory committee for the Conference Series on Recent Progress in Many-Body Theories since 1981, and member of the international advisory committee and executive board of the International Workshops on Condensed Matter Theories since 1981, among other organizations.

To remain abreast of developments in the field, Dr. Clark was the former chairman of the Wheatley Prize selection committee with the American Physical Society from 1998 to 2001, as well as the Academy of Sciences, the Neural Network Society and Phi Beta Kappa. Among his notable achievements, Dr. Clark is most renowned for discovering a method of correlated basis functions for strongly interacting quantum many-body systems and developing theories of non-Fermi-liquid behavior in condensed matter systems. He has also contributed to mathematical foundations of quantum control and conducted research in theories of superdense matter in neuron stars and in models of neural information processing and machine-learning innovations. He has edited 10 books and three special journal issues, and authored more than 320 articles to professional journals.

As a testament to his success, Dr. Clark has received myriad accolades and honors. A fellow of the Alfred P. Sloan Foundation, Von Barclomb Foundation and Schlumberger Foundation, he was a frequent grantee of the National Science Foundation between 1970 and 2004. In 1987, he received the Eugene Feenberg Medal for Many-Body Physics from the international advisory committee for the Conference Series on Recent Progress in Many-Body Theories, which he cites as a career highlight. Likewise, he was featured in the 61st and 62nd editions of Who’s Who in America in 2006 and 2007, respectively.

Married to Carolina Adrianna van den Berk since 1973, Dr. Clark is the proud father of six children and five grandchildren. In his spare time, he enjoys high-performance cars and reading science fiction.
