Impact on the world
Co-founded the International Study Group on Ethnomathematics in 1985, serving as its first president for eleven years, after developing a teaching approach grounded in finding mathematics within everyday cultural practices, most notably her analysis of the geometric patterns in African American women's hair braiding traditions as a tool for teaching geometry and entrepreneurial skills; she became the first African American woman appointed to the Mathematical Association of America's board of governors in 1980 and, in 1992, the first woman to deliver the National Association of Mathematicians' Cox-Talbot Address, named for Elbert Cox and William Claytor, both already profiled in this collection.
Life & background
Born in Baltimore, Maryland in 1928, Gilmer studied under mathematician Clarence Stephens at the historically Black Morgan State University, earning her bachelor's degree in 1949 before completing a master's degree at the University of Pennsylvania in 1951; she briefly conducted ballistics research for the U.S. Army before dedicating herself to teaching, working across six different historically Black colleges and universities as well as public schools, grounding her later pedagogical philosophy directly in the deep mentorship she had received within segregated Baltimore's own Black educational community. After marrying and raising children, she returned to graduate study later in her career, earning a PhD in curriculum and instruction from Marquette University in Milwaukee; her doctoral and subsequent research increasingly focused on ethnomathematics, the study of how mathematical thinking is embedded within specific cultural practices rather than existing as an abstract, culturally neutral discipline, work she described simply as finding 'the math of the people.' She served as a research associate at the U.S. Department of Education from 1981 to 1984, chaired a joint American Mathematical Society, Mathematical Association of America, and American Association for the Advancement of Science committee on expanding minority participation in mathematics, and co-founded the International Study Group on Ethnomathematics in 1985, leading the organization for over a decade and remaining on its executive board for years afterward. She died in Milwaukee in 2021 at age 93, and in 2022 became the first Black woman mathematician to have her research papers acquired by the Library of Congress's Manuscript Division, a collection spanning 176 boxes of correspondence, speeches, research files, and detailed daily logs that her own daughter said she never imagined would be recognized at that level.
