As a recent film featuring NASA mathematician, Katherine Johnson,
points out, math-women often are:
Hidden figures:
women no one
notices are
changing the world.
Although not mathematical, "Diving into the Wreck"
by Adrienne Rich (1929-2012) also is relevant here.
Here is a link to an important article by Judy Green, "How Many Women Mathematicians Can You Name?" Green, now an emeritus professor at Marymount University, opens her article (first published in Math Horizons in 2001) with the admission that until her last undergraduate semester the only female mathematician she could name is Emmy Noether. Green's article, and a book she has co-written (with Jeanne LaDuke) and its companion website, help to remedy such situations for others. There are many important math women to know!
AND, if you still have time after exploring the links above,
please visit my article (with poetry) "They Say She Was Good -- for a Woman,"
published July 2017 in the online Journal of Humanistic Mathematics.
