text: The University of Illinois at Urbana–Champaign awarded Hamming his Doctor of Philosophy in 1942, and he became an instructor in mathematics there. He married Wanda Little, a fellow student, on September 5, 1942, immediately after she was awarded her own Master of Arts in English literature. They would remain married until his death, and had no children. In 1944, he became an assistant professor at the J.B. Speed Scientific School at the University of Louisville in Louisville, Kentucky.
  Manhattan Project
  With World War II still ongoing, Hamming left Louisville in April 1945 to work on the Manhattan Project at the Los Alamos Laboratory, in Hans Bethe's division, programming the IBM calculating machines that computed the solution to equations provided by the project's physicists. His wife Wanda soon followed, taking a job at Los Alamos as a human computer, working for Bethe and Edward Teller. Hamming later recalled that:
  Hamming remained at Los Alamos until 1946, when he accepted a post at the  Bell Telephone Laboratories (BTL). For the trip to New Jersey, he bought Klaus Fuchs's old car. When he later sold it just weeks before Fuchs was unmasked as a spy, the FBI regarded the timing as suspicious enough to interrogate Hamming. Although Hamming described his role at Los Alamos as being that of a "computer janitor", he saw computer simulations of experiments that would have been impossible to perform in a laboratory. "And when I had time to think about it," he later recalled, "I realized that it meant that science was going to be changed".
