Sophie Germain
The prize from the Academy, however, was of immediate importance because it introduced her into the ranks of the prominent mathematicians of the time. She became the first woman who was not a wife of a member to attend the Academy of Sciences' sessions. She was also praised by the Institut de France and was invited to attend their sessions. Sophie continued working with well-known male mathematicians in the 1820s as an "equal collaborator" to refine her proofs and work in number theory; and also continued to work in philosophy until her death, in 1831.
