Thomas Chrowder Chamberlin

Chrowder Thomas Chamberlin ( born September 25, 1843 in Mattoon, Illinois, † November 15, 1928 in Chicago, Illinois) was an American geologist.

From 1873 to 1882 he was a professor at Beloit College in Wisconsin. He also worked for the United States Geological Survey. From 1887 to 1892 he was president of the University of Wisconsin, 1892 to 1918, he worked as a professor at the University of Chicago. During this time, he was from 1898 to 1914 and President of the Chicago Academy of Sciences.

Chamberlin developed the Planetesimaltheorie, the Forest Ray Moulton later further developed. He founded in 1893 the Journal of Geology, whose editor he was for many years. In 1927 he received the first winner of the Penrose Medal of the Geological Society of America.

He also justified the use of multiple hypotheses in the generation of knowledge ( 1890), since the investigation of a single hypothesis would influence the thought process of a researcher too.
