George A. (George Amos) Miller

Born in Pennsylvania in 1863, George Abram Miller worked as a schoolteacher while earning his education, eventually taking degrees from Muhlenberg College and a Ph.D. from Cumberland University. He went on to study with Frank Nelson Cole and later heard major European mathematicians such as Sophus Lie and Camille Jordan during a trip abroad, experiences that helped shape his mathematical career.

Miller became known for his research in group theory, a field in which he was one of the notable American contributors of his era. He taught at several universities, including Michigan, Cornell, Stanford, and, most prominently, the University of Illinois, where he served for many years and remained associated after retirement.

Beyond his research, he played an important part in the broader mathematical community. He served as president of the Mathematical Association of America from 1921 to 1922, gave a plenary address at the 1924 International Congress of Mathematicians, and also wrote on the history of mathematics. His collected works were published by the University of Illinois after his retirement, reflecting the esteem he had earned among colleagues.
