Gerhart Jander

Gerhart Jander August ( born October 26, 1892 in Altdöbern; † December 8, 1961 in Berlin) was a German chemist.

Curriculum vitae

Jander visited the classical language high school Ernestinum in Rinteln, where he graduated from high school in 1912 took off. He studied chemistry in 1912 in Munich and Berlin. In 1917 he received his doctorate with a dissertation about the telluric acid and its alkali metal salts in their behavior than half colloids at Ernst Otto Beckmann and Siegmund Gabriel in Berlin. From 1918 to 1922 he was an assistant to Richard ZSIGMONDY and Adolf Windaus in Göttingen. In 1921 he qualified as a professor and department head in 1922 of inorganic chemistry at the University of Göttingen. In 1925 he was appointed extraordinary professor there. In the same year he joined the NSDAP again approved. On 25 April 1931, he participated as a research assistant at the annual meeting of the warfare agent researchers in part to the development of new poison gases. After the " seizure of power" of the Nazis, he was in 1933 as successor to the crowded from office Fritz Haber Acting Director of the Kaiser Wilhelm Institute for Physical Chemistry in Berlin (now the Fritz Haber Institute of the Max Planck Society). In 1935 he became a full professor and director at the University of Greifswald, where he remained until 1951. From 1951 until his retirement in 1960 he was the director at the TU Berlin.

Jander was married and had two children. The son also studied chemistry.

Work

In the 1920s and 1930s to Jander dealt with the development of Conductometry for quantitative analysis. He was influential leader of this method in the analysis. Important are his conductometric work with sulfur dioxide. Jander research on iso-and hetero - poly acids and polybases and took advantage of many physicochemical processes ( Conductometry, determination of diffusion coefficients, potentiometric and thermometric titration). He examined the conversion of mono-anions to polyanions ( for aluminum, chromium and iron ions). Another area was the provision of dialysis and diffusion coefficients, production of membrane -, ultra fine filters. Jander founded on a textbook on inorganic chemistry, which is used after several updates today under the symbol Jander / Blasius as a textbook in undergraduate chemistry.
