Oppenheimer's Crisis

While Director of Los Alamos Scientific Laboratory between 1943 to 1945, J. Robert Oppenheimer and his wife Kitty would ride two days on horseback from the mesa to his summer home in the Pecos, "much to the dismay of the FBI agents who had to accompany them." Oppenheimer frequently rode a spooky horse aptly named "Crisis."
