:J. Robert Oppenheimer shouldered burdens both large and small, managing the numerous mundane matters such as living quarters, mail censorship, salaries, promotions, and other "quality of life" issues that were inevitable in an intellectual pressure-cooker with few social amenities. J. Robert Oppenheimer Oppenheimer relied on a group of advisers to help him keep the "big picture" in focus, while a committee made up of Los Alamos group leaders provided day-to-day communications between divisions.

Three to four scientists under Oppenheimer's supervision leaked secret information about the atomic bomb to the communist Soviet Union.  These include [[Klaus Fuchs]], [[Theodore Hall]], and [[David Greenglass]].<ref>http://www.lanl.gov/history/wartime/spies.shtml</ref>  Secret Soviet Union documents reviewed in the 1990s reveal a fourth spy, code-named [[Perseus]], who was also at Los Alamos during Oppenheimer's tenure.  This spy was apparently at a high level but has never been identified, and could have been Oppenheimer himself.<ref>''Id.''

Oppenheimer's best-known scientific contribution was to suggest a limit to the size of neutron stars. Larger neutron stars would collapse into [[black holes]] according to the theory of relativity.
