Heinrich Ritthausen

Karl Heinrich Leopold Ritthausen (born January 13, 1826 in Armenruh near Goldberg ( Silesia ), † October 16, 1912 in Berlin ) was a German agricultural chemist.

Life

After attending the Freiherrlich von Fletcher's teachers' seminar, Ritthausen studied chemistry at the University of Leipzig , did his doctorate there in 1853 and worked at the Agricultural Research Station in Möckern from 1854 to 1856. From 1858 to 1868 he worked as a professor of agricultural chemistry at the Agricultural Academy Waldau near Königsberg and then for five years at the Agricultural Academy in Bonn-Poppelsdorf. From 1873 to 1899 he taught as a full professor for agricultural chemistry at the University of Königsberg .

His scientific interest was predominantly protein research. He published most of the results of his experiments in the "Reports of the German Chemical Society". In Königsberg, Ritthausen succeeded for the first time in 1866 in isolating the amino acid glutamic acid from the gluten proteins of the grain by means of sulfuric acid digestion . He gave the crystals obtained in the process to Gustav Werther , Professor of Chemistry in Königsberg , who was then able to define the composition for further analysis . After Ritthausen moved to Bonn, the structure was determined by his assistant, the German chemist Wilhelm Dittmar, at his instigation .

Ritthausen was a Freemason and from 1859 to 1868 a member of the Königsberg Lodge Zum Todtenkopf and Phoenix .

Heinrich Ritthausen died in Berlin in 1912 at the age of 86. He was buried in the Kaiser Wilhelm Memorial Cemetery in Charlottenburg (today's district of Berlin-Westend ). The grave has not been preserved.
