Template:Short description Template:Infobox scientist

Corwin Herman Hansch (October 6, 1918 – May 8, 2011)<ref name="LATIMES-OBIT">Template:Cite news</ref> was a professor of chemistry at Pomona College in California. He became known as the 'father of computer-assisted molecule design.'<ref name="Archive-Guide">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Education and careerEdit

Hansch was born on October 6, 1918, in Kenmare, North Dakota. He earned a BS from the University of Illinois in 1940 and a PhD from New York University in 1944. He briefly worked as a postdoc at the University of Illinois Chicago.

Hansch worked on the Manhattan Project at the University of Chicago and as a group leader at DuPont Nemours in Richland, Washington. In February 1946 he received an academic position at Pomona College, where he taught until 1988.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Hansch completed sabbaticals at ETH Zurich with Vladimir Prelog and at University of Munich with Rolf Huisgen.<ref name=Selassie />

Hansch taught Organic Chemistry for many years at Pomona College, and was known for giving complex lectures without using notes. His course in Physical Bio-Organic Medicinal Chemistry was ground-breaking at an undergraduate level.

Hansch may be best known as the father of the concept of quantitative structure-activity relationship (QSAR), the quantitative correlation of the physicochemical properties of molecules with their biological activities.<ref>Template:Cite journal</ref>

He is also noted for the Hansch equation, which is used in

Multivariate Statistics - Multivariate statistics is a set of statistical tools to analyse data (e.g., chemical and biological) matrices using regression and/or pattern recognition techniques.
Hansch Analysis - Hansch analysis is the investigation of the quantitative relationship between the biological activity of a series of compounds and their physicochemical substituent or global parameters representing hydrophobic, electronic, steric and other effects using multiple regression correlation methodology.
Hansch-Fujita <math>\pi</math> constant - The Hansch-Fujita <math>\pi</math> constant describes the contribution of a substituent to the lipophilicity of a compound.

Research Interests: Organic Chemistry; Interaction of organic chemicals with living organisms, Quantitative Structure Activity Relationships (QSAR).

Fragment based regression analysis for quantitative structure-activity relationship (Hansch-analysis)

DeathEdit

He died of pneumonia on May 8, 2011, in Claremont, California, at 92.<ref name="LATIMES-OBIT" />

NotesEdit

His research group at Pomona College worked on QSAR studies and in building and expanding the database of chemical and physical data as C-QSAR and Bioloom. His postgraduate associates were Rajni Garg, Cynthia R. D. Selassie, Suresh Babu Mekapati, and Alka Kurup.

The Journal of Computer-Aided Molecular Design carried four obituaries (as found in a Pubmed personal subject [ps] search).<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref name=Selassie>Template:Cite journal</ref>

Among his students at Pomona was Jennifer Doudna, co-recipient of the 2020 Nobel Prize in Chemistry. Doudna has credited Hansch as an influence.<ref name=pnasbio>Template:Cite journal</ref>
