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]
