Keller is best known as the editor of William Graham Sumner’s papers in many volumes published in the early 20th century by Yale University Press. He was scholar in his own right and wrote on German colonial policy, economic geography, and sociology.
Keller came from Springfield, Ohio. He graduated from Yale College in 1896 and received his Ph.D. from Yale in 1899. He immediately joined the social science faculty at Yale and was appointed professor in 1907, succeeding his mentor, and taught at Yale until 1942.
Yale's eclectic approach to social science during Keller's time is illustrated by the Festschrift for Keller, edited by George Peter Murdock, presented to Keller in celebration of his completion of 30 years as professor of the science of society in Yale University (New Haven: Yale University Press, 1937) and consisting of essays by 26 scholars who studied with Keller at Yale.
