William E. Tewes

William E. Tewes worked on the gaseous diffusion process at the Nash Garage Building under Dr. Francis Slack, testing the barrier material. He recalls the Nazi invasion of Poland and how the attack on Pearl Harbor brought the country together. In July 1945 Tewes was transferred from New York, where he was working on gaseous diffusion, to Oak Ridge. He worked on the leak testing operation at K-25. He discusses the many scientific and engineering innovations of the K-25 Plant, raising a family in Oak Ridge, and the friends he made among his fellow Manhattan Project workers.
