[Interviewed by S. L. Sanger, from Working on the Bomb: An Oral History of WWII Hanford, Portland State University, 1995]
I shouldn't boast but it is generally said, you see, I was in charge of the group which designed the reactors built at Hanford, and these reactors really worked. Fermi constructed the first nuclear reactor that really was reacting, but it had virtually no energy. And Alvin Weinberg, he designed almost alone the Oak Ridge pilot reactor. But the bigger reactors, we all designed together.
