Harald Schäfer (chemist)
Harald Schäfer (born February 10, 1913 in Jena , † December 21, 1992 in Münster , Westphalia ) was a German chemist and professor of inorganic chemistry at the University of Münster .
Life
Schäfer attended secondary school in Jena and initially trained as a chemical laboratory assistant at the Schott & Gen glassworks. After passing a gifted test, he began studying chemistry in 1937, which he completed in 1940 with a doctorate under Adolf Sieverts . His dissertation was on analytical chemistry by Bor. After serving as an assistant at the University of Jena , in 1945 the Americans forcibly brought him to the West like other scientists at the university. He worked for a short time as an entrepreneur with Helmut Bredereck and in 1948 became department head at the Max Planck Institute for Metals Research in Stuttgart. In the same year he completed his habilitation at the Technical University of Stuttgart with a habilitation thesis on iron oxide chlorides, where he discovered a phenomenon he called chemical transport (migration in the solid body via the gas phase).
In 1953, Harald Schäfer accepted an appointment as an associate professor at the Inorganic-Chemical Institute of the University of Münster, was appointed as a personal professor in 1959 and as a regular professor in 1963 (he declined calls to Graz, Vienna, TU Berlin). From 1964 until his retirement in 1979 he was director of the institute (as successor to Wilhelm Klemm ) and was also dean of the Faculty of Mathematics and Natural Sciences in 1964/65. Schäfer died in Münster in 1992.
research
Harald Schäfer is known for his work on transport reactions in the context of solid-state chemistry. a. are important for the purest preparation of chemical compounds and for crystal growth . Studies on heterogeneous equilibria and chemistry at high temperatures are closely related to this field of work. His research also gave the exploration of cluster compounds significant impulses, and he is particularly concerned with the chemistry of niobium and tantalum . At the end of the 1960s, he founded the field of gas phase complexes.
In 1965 he founded the shirt sleeve colloquium (HÄKO) in solid-state chemistry with Wilhelm Klemm in Münster, which has been held annually at different locations since then.
