As part of my growing up in Brooklyn (NY), I earned a B.A. in mathematics from Brooklyn College and a M.A. at Johns Hopkins University.
I began studying mathematics for my doctorate...but then gave-in and resigned when the university suggested that women in the graduate program should give up their fellowships so they could be given to men returning from WWII.
Spending the next twenty years raising a family, I eventually returned to Johns Hopkins to complete my Ph.D. dissertation on "Absolute Reducibility of Maps of at Most 19 Regions"...at the age of 47.
My contributions in graph theory and homomorphisms, especially regarding chromatic polynomials, are recognized as "influential"... and became foundations for the computer solution (1976) of the four-color conjecture.
While teaching mathematics at George Washington University, I joined a class-action lawsuit to protest inequalities in promotion and pay for female faculty members....it was successful.
In the 1970s, I obtained a NSF grant to start a master’s degree program in teaching mathematics, trying to better prepare the mathematics teachers in Washington, D.Cc public schools.
Finally, one of my daughters, Gina, became a renown mathematical and science journalist for the New York Times.
