Polykarp Kusch was a German-American physicist. In 1955, the Nobel Committee gave a divided Nobel Prize for Physics, with one half to going to Kusch for his accurate determination that the magnetic moment of the electron was greater than its theoretical value, thus leading to reconsideration of—and innovations in—quantum electrodynamics.
Stephen William Hawking CH CBE FRS FRSA is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation, often called Hawking radiation.

He is a vigorous supporter of the many-worlds interpretation of quantum mechanics.
