May Lansfield Keller (September 28, 1877 − June 28, 1964) was a college professor and dean. Born in Baltimore, Maryland to Wilmer Lansfield Keller and Jeanie née Simonton, May Lansfield Keller received an early private school education at the Little Dames' School in the Baltimore area. From 1888 to 1894, she studied at the Girls' Latin School, then matriculated to Goucher College in 1894. She joined Pi Beta Phi, and would remain active in the sorority past her graduation in 1898. At this point she became interested in taking graduate studies in Germany, but her father was opposed so she instead enrolled at the University of Chicago in the fall of 1898. However, she didn't appreciate how women were treated at the institution.
