Arthur Rudolf Hantzsch (7 March 1857 – 14 March 1935) was a German chemist.
Hantzsch studied chemistry in Dresden and graduated at the University of Würzburg under Johannes Wislicenus. As a professor, he taught at the Universities of Zürich, Würzburg und Leipzig.
The Hantzsch pyridine synthesis,[1] a multi-component organic reaction, is named after him, as is the Hantzsch pyrrole synthesis and the Hantzsch thiazole synthesis.[2]
His surname is correctly pronounced /Haːntʃ/ (rhymes with cattle ranch).
