Anton Köllisch (16 March 1888 – September 1916) was a German chemist who, whilst working at Darmstadt for pharmaceutical giant Merck, first described the synthesis of the chemical MDMA.
[1] In 1911, Köllisch published his doctoral dissertation on the topic of indole synthesis from hydrazones under Otto Diels at the University of Berlin.
[2][3] While at Merck, Dr Köllisch was involved in investigating syntheses for methylhydrastinine and hydrastinine.
A procedural patent was filed on Christmas Eve 1912 relating to these syntheses, which mentioned MDMA without name as a chemical intermediate.
