Bill Wilcox, who served as the Official Historian for the City of Oak Ridge, discusses the origins of Oak Ridge during the Manhattan Project. A chemistry graduate from Washington & Lee University in 1943, he was hired by Tennessee Eastman on a "Secret, secret, secret!" project in an unknown location he and his friends nicknamed "Dogpatch." He recalls the amazing construction activity going on at Oak Ridge when he arrived at the site in October 1943. He worked with uranium, which was referred to only by its codename "Tuballoy," under threat of imprisonment. Wilcox worked at Y-12 for five years and then at K-25 for 20 years, retiring as Technical Director for Union Carbide Nuclear Division. Wilcox has actively promoted preservation of the "Secret City" history through the Oak Ridge Heritage & Preservation Association and by founding the Partnership for K-25 Preservation. He also published several books on Oak Ridge, including a history of Y-12 and "Opening the Gates of the Secret City."
