John Wheeler

John Archibald Wheeler was an American theoretical physicist who served as a professor at Princeton University from 1938 to 1976 and later as director of the Center for Theoretical Physics at the University of Texas at Austin until 1986. He is best known for coining the term "black hole," for his work with Niels Bohr on nuclear fission, and for his "it from bit" philosophy proposing that all physical reality is fundamentally information-theoretic in origin. He passed away on April 13, 2008, at the age of 96.
