Fig. 2.15 Gerold Schwarzenbach (1904-1978) did his Ph.D. in 1928 at the ETH Zurich with Professor William D. Treadwell in analytical chemistry and, after a year with Sir Robert Robinson at Manchester and London, became Oberassistent at the Chemische Institut of the University of Zurich. In the 1930s he started his work on the coordination capabilities of a new class of polydentate ligands (Komplexone) which soon received world-wide recognition. In 1942, he was promoted as Associate Professor and in 1947 as Professor of Analytical Chemistry at the University of Zurich but returned in 1955 to the ETH, where he was the Director of the Laboratory of Inorganic Chemistry until his retirement in 1973 (photo from Helv.

Tertiary amines that also contain carboxylic acid groups form remarkably stable chelates with many metal ions. Gerold Schwarzenbach first recognized their potential as analytical reagents in 1945. Since this original work, investigators throughout the world have described applications of these compounds to the volumetric determination of most of the metals in the periodic table. 

B. After the War, Gerold Schwarzenbach, at the University of Zurich, investigated this compound and introduced it as a titrant in 1951.
