Hans Joachim von Wartenberg
Hans Joachim von Wartenberg (born March 24, 1880 in Kellinghusen , † October 4, 1960 in Göttingen ) was a German chemist ( inorganic chemistry , physical chemistry ).
Life
His parents were the Prussian judiciary and court judge Heinrich Karl Hardwig Wolfgang von Wartenberg (born August 8, 1851) and his first wife Martha Johanna Kaestner (born April 29, 1858). His parents' marriage divorced in 1894.
From 1899 Hans Joachim von Wartenberg studied natural sciences and especially chemistry at the University of Berlin and under Walter Nernst in Göttingen and Berlin, where he received his doctorate in Berlin in 1902 (contribution to knowledge of mercury oxyhalides). After his habilitation in 1908, he became head of department at the Institute for Physical Chemistry at the University of Berlin and in 1910 an associate professor. In 1913 he became a full professor for physical chemistry at the Technical University of Danzig and in 1916 a full professor for inorganic chemistry. From 1932 he was a full professor for inorganic chemistry in Göttingen (as the successor to Richard Zsigmondy and Gustav Tammann ), where he was forced to retire by the National Socialists in 1936. He then continued to work in Göttingen at the institute of the solid-state physicist Robert Wichard Pohl . In 1945 he got his chair back and was retired in 1949.
He was a pioneer in the study of chemical equilibria at high temperatures. To this end, he developed micro-measuring processes and methods to measure the smallest amounts of gas. He determined vapor pressures and boiling points for many salts, metals and elements, provided reliable thermodynamic data on chlorine dissociation and oxygen dissociation and the oxygen-ozone equilibrium at high temperatures. His investigation of equilibria in acetylene chemistry also had technical applications.
At the beginning of the 1950s, he was involved in studies that were important for solid-state physics and aimed at producing pure silicon.
In 1910 he married Gertrud Warburg (1886–1971), Otto Warburg's sister.
Honors
In 1951 he was awarded the Bunsen medal of the German Bunsen Society for Physical Chemistry .
