From MIT Institute Archives and Special Collections: "A specialized radar training program, part of a broader Engineering Defense Training (EDT) program sponsored by the U.S. government, was organized at MIT by the Department of Electrical Engineering in June 1941. The focus at MIT was to educate a core group of army and navy personnel about the theory and operation of microwave radar so that they could be ready to use nascent radar technology that was expected to be essential to forthcoming military efforts."
