 Weinberg taught courses at Wright Junior College . He applied for and received a National Research Council fellowship to study under Kenneth S. Cole at Columbia University , but never took it up , as Cole came to Chicago to work on the Manhattan Project as a radiation biologist . Weinberg was recruited to work at its Metallurgical Laboratory at the University of Chicago in September 1941 by Eckart and Samuel Allison , who needed someone to work on the latter 's neutron capture calculations .
