Why did physicist Edward Witten win the Fields Medal?

In 1990, American theoretical physicist Edward Witten became the first physicist ever to win the Fields Medal, one of mathematics' highest honors. He was awarded the prize by the International Mathematical Union for his profound mathematical insights arising from physics. Key achievements cited included his 1981 proof of the positive energy theorem in general relativity and his interpretation of knot Jones invariants as Feynman integrals.
