Wheeler's graduate students included Katharine Way, Richard Feynman, David Hill, Bei-Lok Hu, Kip Thorne, Jacob Bekenstein, John R. Klauder, william Unruh, Robert M. Wald, Arthur Wightman, Charles Misner and Hugh Everett. Wheeler gave a high priority to teaching, and continued to teach freshman and sophomore physics, saying that the young minds were the most important. With Kent Harrison, Kip Thorne and Masami Wakano, Wheeler wrote Gravitation Theory and Gravitational Collapse (1965). This led to the voluminous general relativity textbook Gravitation (1973), co-written with Misner and Thorne. Its timely appearance during the golden age of general relativity and its comprehensiveness made it an influential relativity textbook for a generation. Wheeler teamed up with Edwin F. Taylor to write Spacetime Physics (1966) and Scouting Black Holes (1996). At Princeton he supervised 46 PhDs, more than any other professor in the Princeton physics department.
