Are the historians not aware that Emmy Noether worked on the general theory of relativity during the years 1915 to 1920? She published a paper which many consider the cornerstone of General Relativity.
Although she was not on the faculty officially, she was working with David Hilbert at the University of Gottingen in Germany. She was invited to join his team of mathematicians who were working on Hilbert's foray into mathematical physics. In fact, many historians today give credit to Hilbert for the "final form" of the equations describing general relativity theory. Apparently, both he and Einstein produced the same equations at about the same time: fall of 1915!
Emmy Noether was there, and this was only the beginning of her illustrious career. . .
