Ray Smith is a noted local historian who worked at Y-12 for decades. The Y-12 National Security Complex is a United States Department of Energy National Nuclear Security Administration facility located in Oak Ridge, Tennessee, near the Oak Ridge National Laboratory. It was built as part of the Manhattan Project for the purpose of enriching uranium for the first atomic bombs. In the years after World War II, it has been operated as a manufacturing facility for nuclear weapons components and related defense purposes. Y-12 is managed and operated under contract by Consolidated Nuclear Security, LLC (CNS), which is composed of member companies Bechtel National, Inc., Lockheed Martin Services, Inc., ATK Launch Systems, Inc., and SOC LLC, with Booz Allen Hamilton, Inc. as a teaming subcontractor. CNS also operates Pantex Plant in Texas. Y-12 is the World War II code name for the electromagnetic isotope separation plant producing enriched uranium at the Clinton Engineer Works in Oak Ridge, Tennessee, as part of the Manhattan Project. Construction began in February 1943 under the management of Stone and Webster. The Y-12 facility began operating in November 1943, separating uranium-235 from natural uranium, which is 99.3% uranium-238, by using calutrons to perform electromagnetic isotope separation. Y-12 separated the uranium-235 for Little Boy, the nuclear weapon that was dropped on Hiroshima, Japan on August 6, 1945. K-25, another facility in Oak Ridge, produced enriched uranium using gaseous diffusion. K-25 did not begin operating until March 1945 and fed slightly enriched uranium to Y-12's Beta Calutrons as the push to obtain enough uranium 235 for Little Boy came in the early summer of 1945. The S-50 Thermal Diffusion Plant at the K-25 site also provided feed material for Y-12's Beta Calutrons. Tennessee Eastman was hired by the Army Corps of Engineers to manage Y-12 during the Manhattan Project. The company transferred scientists from Kingsport, Tennessee to Y-12 and operated the plant from 1943 to May 1947.[5] The Y-12 electromagnetic plant units were initially operated by scientists from Berkeley to remove bugs and achieve a reasonable operating rate. They were then turned over to trained Tennessee Eastman operators who had only a high school education. Nichols compared unit production data, and pointed out to physicist Ernest Lawrence that the young "hillbilly" girl operators were outproducing his PhDs. They agreed to a production race and Lawrence lost, a morale boost for the Tennessee Eastman workers and supervisors. The girls were "trained like soldiers not to reason why", while "the scientists could not refrain from time-consuming investigation of the cause of even minor fluctuations of the dials".…

An archive of 10 original posters for productions staged by Ray Bradbury's Pandemonium Theatre Company from 1988 to 2004. The plays were performed in Southern California, predominantly at The Court Theatre, Falcon Theatre, Theatre West, The Raven Playhouse, and Melrose Theatre. The archive includes posters from 10 productions, including "Fahrenheit 451," "The October Country," "Past, Present & Future," "The Time of Going Away," and "Drunk and In Charge of a Bicycle." and his Irish play "Falling Upward!" "Falling Upward!" was one of Bradbury's favorite plays, and especially as he advanced in age he was know to encourage its frequent production simply for the joy of being able to see it again. Bradbury was an avid playwright and a familiar and enthusiastic presence in the Southern California theatre circuit near his home. In 1963 he and director Charles Rome Smith founded Pandemonium Theatre Company. The two friends would go on to work with the company together for the next four decades, until Rome's death in 2004. This archive is a solid representation of the company's latter half, before Smith's passing and Bradbury's hearing loss, which would necessitate that he stop attending performances. Posters approximately 11 x 17 inches. About Fine condition.…
