Gustav Körtum

Gustav Ferdinand Albert Kortüm (14 June 1904 to 1 December 1990) was a German physical chemist.

Kortüm was the son of a pastor and studied chemistry at Karlsruhe Institute of Technology from 1922. In 1928 he received his doctorate under Georg Bredig with a thesis on the knowledge of hydrocyanic acid synthesis from carbon monoxide and ammonia. He then worked as a postdoctoral researcher at the Kaiser-Wilhelm-Institut für Physical Chemistry and Electrochemistry in Berlin and from 1929 was assistant to Johannes Ludwig Ebert in Würzburg. From 1931 he was an assistant to Hans von Halban at the University of Zürich. From 1937 he taught at the University of Tübingen, where he became full professor in 1942 and director of the newly created institute for physical chemistry. He became an emeritus professor in 1971.

He focused on spectrophotometry, electrochemistry, and electrolyte solutions (reviewing the Debye-Hückel theory and Onsager's theory of solvent mixtures), vapor pressure measurements on binary systems, and reflection spectroscopy. In 1959 he was elected a member of the Leopoldina.
