Edward Witten (born August 26, 1951) is a mathematical and theoretical physicist from the United States. He is Professor Emeritus of Natural Sciences at Princeton's Institute for Advanced Study. Witten studies string theory, quantum gravity, supersymmetric quantum field theories, and other branches of mathematics. Witten's work has also had an impact on pure mathematics. He was the first physicist to receive the International Mathematical Union's Fields Medal in 1990 for his mathematical contributions to physics, such as his 1981 proof of the positive energy theorem in general relativity and his interpretation of the Jones invariants of knots as Feynman integrals. He is widely regarded as the practical founder of M-theory.
