Bernhard Schlegel

Hans Bernhard "Berny" Schlegel (born September 24, 1951) is German-born computational and theoretical chemist, and distinguished professor at Wayne State University. He is a highly cited chemist, with a Thomson Reuters H-Index of 116 and citations of over 218,000 as of 2020. He is a professor of chemistry at the Wayne State University and co-author of the computational chemistry software, Gaussian. The "Berny optimization" as implemented in Gaussian is named after him. His group also created the Electronic Structure Perl Toolkit (ESPT).

Schlegel was born in Frankfurt am Main, and immigrated to Canada with his family at the age of four. He was raised in Windsor, Ontario, and graduated from the University of Waterloo in 1972. Schlegel earned a doctorate three years later, from Queen's University at Kingston, advised by Saul Wolfe, then pursued postdoctoral research with Kurt Mislow and at Princeton University before moving to Carnegie Mellon University to work with John Pople. Between 1978 and 1980, Schlegel was employed at Merck, Sharp, and Dohme Research Laboratories. Subsequently, Schlegel began his academic career at Wayne State as an assistant professor. He became a full professor in 1986, and a distinguished professor in 2011.

Schlegel has won the ACS Award for Computers in Chemical and Pharmaceutical Research and he is a Fellow of the American Association for the Advancement of Science, Fellow of the Royal Society of Chemistry, Fellow of the American Chemical Society and Academy of Scholars of Wayne State University, among others.

He has co-authored more than 400 peer-reviewed publications.
