Hans P. Eugster

from Wikipedia, the free encyclopedia

Hans Peter Eugster (born November 19, 1925 in Igis , Switzerland ; † December 17, 1987 in Baltimore , USA ) was a Swiss-American mineralogist , petrologist and geochemist .

Eugster studied at the ETH Zurich with his diploma in 1948 and his doctorate with Paul Niggli in 1951, studying metamorphic recrystallization in the eastern part of the Aar massif for his dissertation . He was a postdoctoral fellow at the Massachusetts Institute of Technology , where he did research with James Burleigh Thompson of Harvard University , and then went to the Geophysical Laboratory of the Carnegie Institution in Washington, DC There, under Hatten Yoder , he worked on experimental mineralogy. He investigated the phase equilibrium of the formation of sheet silicates such as various mica (whereby he developed a technique to control the oxygen fugacity and thus the chemical composition) and evaporites of the Green River Formation, later followed by worldwide investigations of other salt deposits. In 1958 he became associate professor of experimental petrology at Johns Hopkins University and in 1960 professor. 1983 to 1987 he was head of the Faculty of Geosciences. He was also from 1970 Adjunct Professor at the University of Wyoming . He died surprisingly of an aortic tear.

He was a member of the National Academy of Sciences (1972) and the American Academy of Arts and Sciences . He received the Roebling Medal in 1983 , the VM Goldschmidt Award in 1976 and the Arthur L. Day Medal in 1971 . In 1985 he was President of the Mineralogical Society of America .

The salt mineral eugsterite from Lake Victoria in Kenya was named after him in 1981.

His brother Conrad Hans Eugster was a chemist and university professor.
