Hans Kautsky

from Wikipedia, the free encyclopedia

Hans Kautsky (born April 13, 1891 in Vienna ; † May 15, 1966 at Kamniška Bistrica) was an Austrian chemist.

The father Hans Joseph Wilhelm Kautsky (1864–1937) was an Austro-Hungarian and royal Prussian court theater painter in Vienna and Berlin. The younger brothers were Robert Kautsky (1895–1963; stage designer at the Vienna State Opera) and Fritz (geologist in Sweden). The grandfather Johann Baptist Wenzel Kautsky (1827-1896) was a painter and stage designer in Prague, his grandmother was the actress and writer Minna Kautsky (1837-1912). His uncle was the social democratic theorist Karl Kautsky (1854–1938).

His son of the same name, born in 1920, became an oceanologist on the Meteor.

Life

Hans Kautsky initially trained as a painter and draftsman, a. a. in Holland. However, he was more interested in chemistry and studied chemistry at the TH Charlottenburg from 1911 to 1917 without a high school diploma . During the First World War he did his military service in a test center that examined the production of gas masks. After the war he worked as an assistant at the Kaiser Wilhelm Institute under Herbert Freundlich and received his doctorate in 1922 with a thesis on unsaturated silicon compounds. In 1928 he completed his habilitation in Heidelberg and in 1934 received an associate professorship for inorganic chemistry. From spring 1936 to 1945 he was professor for inorganic structural chemistry at the University of Leipzig . In June 1945 the Americans brought him to Weilburg / Lahn. From 1947 he rebuilt the Institute for Inorganic Chemistry at the University of Marburg , where he then held a chair.

Scientific work

The focus of his scientific work was silicon chemistry . In particular, he investigated the formation of siloxene, a polymeric two-dimensional compound of silicon, oxygen and hydrogen, from calcium disilicide (CaSi 2 ). In addition, he dealt with lepidoid silicas with a view to their possible use in catalysis . He was also interested in surface chemistry , specifically under the aspect of energy conversions on surfaces ( fluorescence , phosphorescence and photochemical reactions). This led him to extensive investigations into chlorophyll fluorescence in connection with the conversion of solar energy into chemical energy during carbon dioxide assimilation .
