Physicist and mathematician Edward Witten is often associated with important names in physics, such as Galileo, Newton and Einstein. From 1980 until 1987, Witten worked as a professor in Physics at Princeton University. He was then appointed professor in Physics at the Institute for Advanced Study at Princeton. He contributed greatly to several areas in theoretical physics. His endeavor to integrate Einstein's theory into quantum mechanics resulted in his 1987 publication on superstring theory. Nowadays, this theory is recognized as an important step towards the final theory on the fundamental building blocks of the universe. In 1990, he was awarded The Fields Medal and in 2010, the Lorentz Medal.
