(Johann) Heinrich Biltz (born May 26, 1865 in Berlin ; † October 29, 1943 in Breslau ) was a German chemist and university professor .

Live and act

Heinrich Biltz was the son of the literary scholar and theater critic Karl Friedrich Biltz and Auguste Schlobach (1839-1883), daughter of the surveyor Tobias Schlobach (1798-1854).

After graduating from the Royal Wilhelm Gymnasium in Berlin in 1885, he studied chemistry first at the University of Berlin with August Wilhelm von Hofmann and later at the University of Göttingen with Victor Meyer . He became a member of the Cimbria Göttingen country team . In 1889 he obtained his doctorate with a continuation of the investigations started by Victor Meyer into the molar masses of substances at high temperatures ( on the molecular size of sulfur and tin chlorine together with a determination of the boiling point of the latter ). Here he determined, among other things, the vapor densities of tin chloride (tin (II) chloride) and sulfur .

From July 8, 1891, he worked as a professor of chemistry, initially at the University of Greifswald and from 1897 at the University of Kiel . There he headed the Inorganics Department until 1911, where he continued his research, especially in the field of vapor density determination. In 1908 in Kiel he succeeded in synthesizing phenytoin , which 30 years later was used as a successful drug to control epileptic seizures. From autumn 1911 until his retirement in 1933 he taught at the newly established Ladenburg Institute of the University of Breslau , focusing on the reaction processes of substances within organic chemistry , in particular the reactions of acetylene and auto-oxidation . Another focus of his research was uric acid chemistry. He succeeded in clearing up the entire oxidative breakdown of uric acid with oxidizing agents .

The service as captain of the reserve during the First World War forced him to take a long break. After the war, the scope of his scientific work grew, in which his younger brother Wilhelm Biltz , also a chemistry professor, and other well-known professors participated at times .

In honor of Heinrich Biltz, the chemical industry established a Biltz Foundation in 1925 to promote talented chemistry students.

In an obituary by Walter Hückel , his services were recognized and a complete bibliography of his works was included.

Biltz was married to the Kiel doctor's daughter Freya de la Motte Fouque. The marriage remained childless.
