Gauss and Germain - Professor Raymond Flood

She was self-taught from books, and from lecture notes supplied by male friends attending the Ecole Polytechnique which Germain, as a woman, was not permitted to attend. Using a male pseudonym, M. LeBlanc, she corresponded with Lagrange who recognised her skill, and subsequently sponsored her work. She accomplished a limited proof of Fermat's last theorem.
