Kellex Corporation
The Kellex Corporation was a wholly owned subsidiary of M. W. Kellogg Company. Kellex was formed in 1942 so that Kellogg's operations relating to the Manhattan Project could be kept separate and secret. "Kell" stood for "Kellogg" and "X" for secret. The new company's goal was to design a facility for the production of enriched uranium through gaseous diffusion. In gaseous diffusion, isotopes of Uranium-235 could be separated from Uranium-238 by turning uranium metal into Uranium hexafluoride, uranium hexafluoride gas and straining it through a barrier material. History The M. W. Kellogg Company, headquartered in Jersey City, New Jersey, specialized in chemical engineering projects. A year before the Manhattan Project began, the S-1 Section of the Office of Scientific Research and Development asked Kellogg to work with John R. Dunning and other scientists at Columbia University to ascertain the feasibility of gaseous diffusion. The pilot project at Kellogg was led by Percival C. ...

Woolworth Building
The Woolworth Building is a residential building and early skyscraper at 233 Broadway (Manhattan), Broadway in the Tribeca neighborhood of Lower Manhattan in New York City. Designed by Cass Gilbert, it was the tallest building in the world from 1913 to 1929, and it remains one of the List of tallest buildings in the United States, United States' 100 tallest buildings . The Woolworth Building is bounded by Broadway and City Hall Park to its east, Park Place to its north, and Barclay Street to its south. It consists of a 30-story base topped by a 30-story tower. Its facade is mostly clad with architectural terracotta, though the lower portions are limestone, and it features thousands of windows.

John R
John R. (born John Richbourg, August 20, 1910 – February 15, 1986) was an American radio disc jockey who attained fame in the 1950s and 1960s for playing rhythm and blues music on Nashville radio station WLAC. He was also a notable record producer and artist manager. Richbourg was arguably the most popular and charismatic of the four announcers at WLAC who showcased popular African-American music in nightly programs from the late 1940s to the early 1970s. (The other three were Gene Nobles, Herman Grizzard, and Bill "Hoss" Allen.) Later rock music disc jockeys, such as Alan Freed and Wolfman Jack, mimicked Richbourg's practice of using speech that simulated African-American street language of the mid-twentieth century. Richbourg's highly stylized approach to on-air presentation of both music and advertising earned him popularity, but it also created identity confusion. Because Richbourg and fellow disc jockey Allen used African-American speech patterns, many listeners thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear History Of The United States
Nuclear history of the United States describes the history of nuclear affairs in the United States whether civilian or military. Timeline Manhattan Project The pre-Hiroshima nuclear history of the United States began with the Manhattan Project. This Manhattan Project was the nuclear program for warfare. Even before the first nuclear weapons had been developed, scientists involved with the Manhattan Project were divided over the use of the weapon. The role of the two atomic bombings of the country in Japan's surrender and the U.S.'s ethical justification for them has been the subject of scholarly and popular debate for decades. The question of whether nations should have nuclear weapons, or test them, has been continually and nearly universally controversial.Jerry Brown and Rinaldo Brutoco (1997).

K-25 Project
K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs using the gaseous diffusion method. Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site. When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, comprising over of floor space and a volume of . Construction of the K-25 facility was undertaken by J. A. Jones Construction. At the height of construction, over 25,000 workers were employed on the site. Gaseous diffusion was but one of three enrichment technologies used by the Manhattan Project. Slightly enriched product from the S-50 thermal diffusion plant was fed into the K-25 gaseous diffusion plant. Its product in turn was fed into the Y-12 electromagnetic plant. The enriched uranium was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clinton Engineer Works
The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium. It consisted of production facilities arranged at three major sites, various utilities including a power plant, and the town of Oak Ridge. It was in East Tennessee, about west of Knoxville, and was named after the town of Clinton, to the north. The production facilities were mainly in Roane County, and the northern part of the site was in Anderson County.
