Robert Carter spent a year and a half as a graduate student at Purdue University before being recruited to work for the Manhattan Project. At Los Alamos, Carter’s team, which included his close friend Joan Hinton, worked on the research reactor. Eventually, Carter and Hinton came to work closely with Enrico Fermi, who became a mentor and friend to the two of them. Carter fondly recounts his dinners and hikes with Hinton and Fermi, both at Los Alamos and after. After the war, Carter enrolled in graduate courses at University of Illinois before returning to Los Alamos for fifteen years. For the rest of his career, Carter worked for various government agencies before retiring. Carter also discusses his friend Harry Daghlian and advising prominent physicist George Gamow on a project.
