Ralph Duncan James
Ralph Duncan James (8 February 1909, Liverpool, England – 19 May 1979, Salt Spring Island, British Columbia, Canada) was a Canadian mathematician working on number theory and mathematical analysis. Born in Liverpool, Ralph moved with his parents to Vancouver, British Columbia when he was 10 years old. After graduating from high school, Ralph attended University of British Columbia. After graduating, he continued in mathematics, writing a master’s thesis on "Tangential Coordinates". Proceeding to University of Chicago, he studied number theory and Waring's problem under L. E. Dickson. In 1932 he was a awarded a Ph.D. on  the strength of his dissertation "Analytical Investigations of Waring's Theorem". He continued post-graduate study, first with E. T. Bell at California Institute of Technology, then in 1934 with G. H. Hardy at Cambridge University. He published in the Transactions of the American Mathematical Society and extended some work of Viggo Brun in 1938. Ralph James was a professor of mathematics at University of California, Berkeley from 1934 to 1939. He was then called to University of Saskatchewan where he became Head of the mathematics department. In 1943 he began his long tenure at University of British Columbia, becoming  Head of the department in 1948. James made contributions to the theory of the Perron integral and to solution of Goldbach's conjecture. Since 1978, the Canadian Mathematical Society have awarded the Coxeter–James Prize in his honor. Papers. Ralph Duncan James published the following papers in the course of his career:
