Enrico Fermi
Fermi was an Italian theoretical and experimental physicist. When Benito Mussolini came to powers, Fermi immigrated to the United States to escape the fascist government. Once arriving in New York, Fermi began teaching at Columbia University. Fermi moved to Chicago University where he created the first self-sustained nuclear reaction under Stagg Field in a squash court. In the summer of 1944, Oppenheimer convinced Fermi to work at Los Alamos with him. Fermi was appointed as associate director and helped lead the project with Oppenheimer, becoming known as one of the "fathers of the atomic bomb." During his career, Fermi won the Nobel Peace Prize and became famous for his work with the Manhattan Project.
