Gloria Ford Gilmer

Lore & Background

Gloria Ford Gilmer was born in Baltimore, Maryland on June 28, 1928. She earned a Bachelor of Science from Morgan State University in 1949. She later earned an MA in Mathematics from the University of Pennsylvania and worked on ballistics research at the Aberdeen Proving Ground. She taught at six HBCUs and studied for a PhD at the University of Wisconsin-Madison but left after a year due to marriage, children, and the need to earn a living. Between 1965 and 1966, she taught mathematics at Milwaukee Area Technical College and the University of Wisconsin–Milwaukee. She later earned a PhD in Education Administration from Marquette University.

Much of Gilmer's later work focused on ethnomathematics. She conducted fieldwork in New York and Baltimore, observing hair stylists and customers to document mathematical patterns in braiding, such as tessellations in box braids and triangular braids. She used these findings to create classroom activities. In the early 1980s, she was the first African American woman on the board of governors of the Mathematical Association of America. From 1981 to 1984, she was a research associate at the United States Department of Education. In 1984, she attended the Fifth International Commission of Mathematical Education in Adelaide, Australia. She was a founding member of the International Study Group on Ethnomathematics in 1985 and served as its president from 1985 to 1996. She was the second person and first woman to give the National Association of Mathematicians' Cox-Talbot lecture.

In 2008, Gilmer became president of Math-Tech, a corporation developing mathematics curricula for women and minorities. In 2022, her papers were archived in the Manuscript Division of the Library of Congress. She died on August 25, 2021, in Milwaukee at age 93.

Reader's Guide

Gloria Ford Gilmer's significance lies in her pioneering role as an African American woman in mathematics and her contributions to ethnomathematics. She was the first African American woman to publish a non-PhD thesis, and her early papers with Luna Mishoe were the first research papers published by an African American woman. Her work in ethnomathematics, particularly documenting mathematical patterns in African American hairstyles, helped bridge cultural practices and formal mathematics education. She used these findings to create classroom activities, making mathematics more accessible and relevant. Gilmer also broke barriers in academic and professional organizations, becoming the first African American woman on the board of governors of the Mathematical Association of America and the first Black woman mathematician archived in the Library of Congress. Her leadership in co-founding the International Study Group on Ethnomathematics and her presidency of Math-Tech underscore her commitment to improving mathematics education for women and minorities. The American Mathematical Society's Claytor-Gilmer Fellowship, named partly after her, continues to honor her legacy.
