Emmy is a German diminutive of Emma. **Amalie Emmy Noether (1882-1935)** is **widely regarded as the most important woman in the history of mathematics** — and one of the greatest mathematicians of the 20th century regardless of gender. **Her *Noether's Theorem* (1918) links every symmetry of physics to a conservation law** — the foundation of modern theoretical physics. **Einstein wrote her obituary in the *New York Times*** calling her "the most significant creative mathematical genius thus far produced since the higher education of women began."
**Subject of Edna Pasternak's *Emmy Noether's Wonderful Theorem* (2011).**
Emmy reduces to six — the number of greatest female mathematician.
