Norman J. Pullman (March 31, 1931 – May 28, 1999) was a mathematician, professor of mathematics, and Doctor of Mathematics, who specialized in number theory, matrix theory, linear algebra, and theory of tournaments.[1][2][3]
Career
He earned an M.A. degree in mathematics from Harvard University, and in 1962, he was awarded the Doctorate degree of Mathematics from Syracuse University. [2]
From 1962 to 1965, he was professor of Mathematics at McGill University. And in 1965 he was awarded a postdoctoral fellowship at University of Alberta.[2]
In 1965 he started to work at the faculty of Queen's University, and held a professorship position since 1971.[2]
He lectured in professional meetings for the American Mathematical Society and the Australian Mathematical Society.
He was a Visiting Scholar for Curtin University of Technology in a great many occasions, and had a professional association with the institution.
During his career, he supervised mathematicians like Dominique de Caen, Rolf S. Rees, and Bill Jackson, among others.[2]
His research included contributions in matrix theory, linear algebra, and theory of tournaments.[2]
