Matilda effect
Suffragist and abolitionist Matilda Joslyn Gage (1826–98) was the first person to write about this effect.  She wrote an essay, "Woman as Inventor." It was first published as a tract in 1870 and in the North American Review in 1883.  The term "Matilda effect" was started in 1993 by science historian Margaret W. Rossiter.
