From the Math Department of the University of Buffalo:

Euphemia Lofton Haynes was a principal and deputy superintendent in charge of Washington’s “colored schools” (the schools for African Americans) before she earned her Ph.D. in Mathematics at The Catholic University in Washington, D.C., in 1943, which made her the first African American Woman to earn a Ph.D. in Mathematics.

The title of her dissertation was “The Determination of Sets of Independent Conditions Characterizing Certain Special Cases of Symmetric Correspondences.”

Dr. Haynes taught in the public schools of Washington, D.C., for 47 years and was the first woman to chair the local school board. She established the mathematics department at Miner Teachers College, where she was also a professor, and was chair of the Division of Mathematics and Business Education at the District of Columbia Teachers College. In 1959, she retired, but served as head of the city’s Board of Education, and was central to the integration of Washington, D.C. public schools.
