Heinrich Fresenius (chemist)
Remigius Heinrich Fresenius , called Heinrich Fresenius, (born November 14, 1847 in Wiesbaden , † February 14, 1920 ibid) was a German analytical chemist.
Heinrich Fresenius was the son of Carl Remigius Fresenius and Charlotte Rumpf, a daughter of the literary scholar Friedrich Karl Rumpf .
From 1866 to 1868 he studied in his father's teaching laboratory. From 1868 he studied chemistry in Berlin and Leipzig with Hermann Kolbe , where he received his doctorate in 1871 with the thesis About Corallin . From 1871 he published the journal for analytical chemistry . Until 1872 he was Kolbe's assistant, then a lecturer in his father's laboratory.
In 1881 his father handed him the directorate of the agricultural research laboratory, which had been founded at his suggestion. In 1897, after the death of his father, he took over the management of the Fresenius Laboratory with his brother Theodor Wilhelm Fresenius and his brother-in-law Ernst Hintz and together with them published the journal for analytical chemistry.
He married Eva Maria Charlotte, geb. v. Heusch (1851-1930). Her sons August Wilhelm Fresenius and Otto Anton Gustav Emil Fresenius (1883–1915) became theologians and captains respectively.
He developed various methods for the detection of metals in fats and oils and methods for electrolytic determination for nickel and cobalt . He found the microchemical evidence for rubidium and the 30 minute water analysis.
