An archaic term for a chemist or alchemist; someone who works with chemical or alchemical processes.
From 'chemick' (archaic form of chemist) + '-er' suffix (from Old English -ere and Germanic roots), indicating a person who does or practices something.
Chemickers occupied a strange social position in medieval and Renaissance Europe—they were part charlatan, part genuine scientist, simultaneously derided and desperately sought out by royalty hoping for gold or cures.
