Arthur Herbert Copeland

Arthur Herbert Copeland (born June 22, 1898 in Rochester , New York , † July 6, 1970 ) was an American mathematician .

Copeland studied at Amherst College ( bachelor's degree in 1921) and received his doctorate in 1926 at Harvard University under Oliver Kellogg on Kreisel ( Studies on the gyroscope ). 1922/23 he was an instructor at Harvard and from 1924 to 1928 at Rice University . In 1928 he was Assistant Professor at the University of Buffalo and in 1929 at the University of Michigan , where he was Associate Professor in 1937 and Professor in 1943. In 1968 he retired.

He dealt with analysis and applications in mechanics, but above all with the fundamentals of probability theory. He also published on Boolean algebras with application in probability theory and advised the US Navy.

The Copeland-Erdős number is named after him and Paul Erdős (published jointly in 1946) - both proved that it is a normal number .

In 1935/36 he was a Guggenheim Fellow . He was a fellow of the Institute of Mathematical Statistics . Howard Raiffa was one of his PhD students .

He was married to Dorothy Eleanor West since 1925 and had a son with her: Arthur Herbert Copeland Jr., Professor of Mathematics at the University of New Hampshire .
