||Grete (Henry-)Hermann (b. April 15, 1984) was a German mathematician and philosopher noted for her work in mathematics, physics, philosophy and education. She is noted for her early philosophical work on the foundations of quantum mechanics, and is now known most of all for an early, but long-ignored refutation of a no-hidden-variable theorem by John von Neumann.
