Professor Emeritus Andrew Streitwieser, University of California, Berkeley, USA, has passed away on February 23, 2022. Streitwieser was well-known for his contributions to physical organic chemistry and considered a pioneer of molecular orbital theory. His book Molecular Orbital Theory for Organic Chemists made a great impact in the field.

Andrew Streitwieser was born in Buffalo, NY, USA, on June 23, 1927. He studied chemistry at Columbia College and Columbia University, New York, USA, where he received his Ph.D. in 1952 under the supervision of William von Eggers Doering. He then served as a Postdoctoral Fellow working with John D. Roberts at the Massachusetts Institute of Technology (MIT), Cambridge, USA. In 1952, he joined the University of California, Berkeley, as an Instructor and served there as Professor of Chemistry until his retirement in 1993.

Among many other awards, Streitwieser received the ACS Award in Petroleum Chemistry in 1967 from the American Chemical Society (ACS), the Alexander von Humboldt Medal in 1979, the ACS James Flack Norris Award in Physical Organic Chemistry in 1982, the ACS Cope Scholar Award in 1989, the Berkeley Citation from the University of California in 1993, and the ACS Roger Adams Award in Organic Chemistry in 2009. He was a Member of the U.S. National Academy of Sciences and the American Academy of Arts and Sciences, a Corresponding Member of the Bavarian Academy of Sciences, and a Fellow of the ACS and the American Association for the Advancement of Science.
