Mathematician:Marie-Sophie Germain

Marie-Sophie Germain was a French mathematician who contributed to differential geometry and number theory, and provided some insights into aspects of Fermat's Last Theorem.

She was completely self-taught (as women were not encouraged to do that sort of thing in those days) and contributed her early work under the pseudonym Monsieur LeBlanc.

Had Gauss and Lagrange as mentors, but apart from that, suffered throughout her career from prejudice against her gender.
