Richmond was born in Dresden on January 30, 1958, earned a vordiplom from the University of Würzburg, and completed her Ph.D. at Florida State University in 1985. Her doctoral dissertation, Freeness of Hopf algebras over grouplike subalgebras, was supervised by Warren Nichols, a student of Irving Kaplansky.She became a professor at Western Kentucky University, teaching there for 23 years. Topics in her mathematical research included abstract algebra, transformation semigroups, ring theory, and Hopf algebra, including the proof of the Nichols–Zoeller freeness theorem in Hopf algebra. With her husband, Thomas Richmond, she was the author of a mathematics textbook, A Discrete Transition to Advanced Mathematics. She also published works in recreational mathematics.
