Georg Lockemann

from Wikipedia, the free encyclopedia

Georg Lockemann (born October 17, 1871 in Hollenstedt (Northeim) , † December 4, 1959 there ) was a German chemist and chemical historian.

Life

His parents were the salt works and mill owners Hermann Lockemann (1838–1905) and Agnes (1845–1906), a daughter of pastor Georg Katenhausen.

Georg Lockemann attended grammar school in Göttingen, studied chemistry at the TH Hannover from 1891 and became a member of the Corps Macaro-Visurgia there. From 1894 he continued his studies at the University of Heidelberg , where he met Robert Wilhelm Bunsen . In 1896 he received his doctorate with an organic-chemical thesis on azobenzene derivatives. He worked briefly at the saltworks in Sülbeck and moved to Leipzig in 1898, where he was private and from 1901 teaching assistant to Ernst Otto Beckmann . Together with Otto Liesche (1878–1931) he experimented with phenylhydrazine and phenylhydrazones . In 1904 he completed his habilitation with studies of acrolein and phenylhydrazine.

In 1907 he became head of the chemical department of the Robert Koch Institute in Berlin. After he retired here in 1937, he was reappointed in this position from 1939 to 1945.

In 1909 he completed his habilitation again at the Agricultural University in Berlin with an improvement in the arsenic detection with the Marsh-Liebig apparatus . In the same year he received a private lectureship here.

From 1921–1945 he taught the history of chemistry and pharmacy at Berlin University. After he returned to his place of birth after the end of the war, he continued teaching in Göttingen from 1946 to 1948. In 1932 he was elected a member of the Leopoldina .

Lockemann was able to prove from 1925 to 1927 that the Haff disease , which occurred from 1924 onwards, was not due to arsenic. He also developed a synthetic breeding ground for the tubercle bacillus.

Of his more than 170 publications, 40 deal with the history of chemistry.
