William C. Krumbein

from Wikipedia, the free encyclopedia

William Christian Krumbein (born January 28, 1902 in Beaver Falls , Pennsylvania , † August 18, 1979 in Los Angeles , California ) was an American geologist ( sedimentology ).

Krumbein grew up near Chicago and studied business administration and then geology at the University of Chicago with a master’s degree in 1930 and a doctorate in 1932 ( The mechanical analysis of related samples of glacial till ). He was associate professor at the University of Chicago and, after military service in World War II, he was with the Army Corps of Engineers and, for a short time in 1945/46 with the Gulf Research and Development Company, from 1946 professor at Northwestern University . In 1970 he retired there.

He applied statistical methods in sedimentology and had a pioneering role in it, including the classification of the roundness of sediment grains. He was one of the founders of the International Association for Mathematical Geology (IAMG), which has been awarding the Krumbein Medal in his honor since 1976. He used computers early and published a geological computer program (SOAP) with Larry Sloss in 1958, the first such publication in a.

In 1977 he received the Twenhofel Medal from the SEPM. In 1979 he received an honorary doctorate from Syracuse University. He was a member of the American Academy of Arts and Sciences (1964) and the Illinois Academy of Sciences and a fellow of the Geological Society of America , whose bulletin he co-edited from 1963 to 1974. In 1950 he was President of the Society of Sedimentology (SEPM). In 1955/56 he was on the Executive Committee of the American Association of Petroleum Geologists.
