Erich Groschuff

from Wikipedia, the free encyclopedia

Erich Groschuff (born October 5, 1874 in Berlin ; † December 9, 1921 in Görbersdorf ) was a German chemist specializing in inorganic chemistry .

Live and act

Groschuff came from an old Berlin legal family. He was the son of the then public prosecutor and later President of the Senate at the Superior Court Albert Groschuff (1835-1903). After graduating from high school in 1897, he studied in Berlin, where he received his doctorate in 1901 with an extensive thesis “On the stereochemistry of the piperidine series: Behavior of the vinyl diacetone and triacetonamine groups against nitrous acid” . He then went - initially as a scientific assistant - to the chemical laboratory of the Physikalisch-Technische Reichsanstalt and was traded as the successor to the head of the chemical laboratory, Franz Mylius , who left in 1919 , which was thwarted by his death after a serious illness.

Tombstone and grave of his father

He is buried in the St. Marien and St. Nikolai Cemetery I in Berlin-Prenzlauer Berg.

Among other things, a process used to this day for coloring copper and brass black ( potassium persulfate process) goes back to Groschuff.
