Prior to joining UNH and serving as dean of Engineering and Physical Sciences (2000-2005), he was the chemistry department chair at the University of North Carolina at Charlotte (1994-2000) and prior to that director of the graduate program in environmental sciences at Rutgers University (1989-1994). He earned his Ph.D. from Princeton University in 1971. He is a Fellow of the ACS and a Fellow of the HIST Division. Most recently he served as Chair of the HIST Division in 2023 and 2024.

He has published more than 140 refereed articles and book chapters, authored four books, and co-authored one book. He is the founding co-editor of the journal Structural Chemistry. Professor Greenberg's most recent book, From Alchemy to Chemistry in Picture and Story, was published by John Wiley and Sons.  

David E. Lewis, Professor Emeritus at the University of Wisconsin-Eau Claire, is an organic chemist whose interests are in organic synthesis and the history of organic chemistry in Russia. He was educated (B.Sc., Ph.D., D.Sc.) at the University of Adelaide, South Australia. He built his independent career in the U.S., retiring in 2022. He is the author of over 110 refereed journal articles and book chapters, 12 open-access columns in Synform, and 7 books; he served as the English-language editor of the English translation of a compendium published in Russia: Beloglazkina, E.; Beletskaya, I.; Lewis, D.; Nenajdenko, V. (Eds.) History of Organic Chemistry at Russian Universities. From Origins to the Present Day; NGB Publishing House: Moscow, 2022. His most recent books areThe Wolff-Kishner Reduction and Related Reactions,Organic Name Reactions. Biographies, Discovery and Development andAddition, Elimination and Substitution: Markovnikov, Hofmann, Zaitsev and Walden. Discovery and Development, both published by Elsevier. He is the American Associate Editor forSynthetic Communications. 

He is a Fellow of the Royal Society of Chemistry and of the Royal Australian Chemical Institute, a HIST Fellow, and former Chair of HIST. He received the 2018 Joseph B.
