In 1942,[12] the United States federal government forcibly purchased nearly 60,000 acres (240 km2) of farmland in the Clinch River valley for the development of a planned city supporting 75,000 residents. It was constructed with assistance from architectural and engineering firm Skidmore, Owings & Merrill, from 1942 to 1943.[13] Oak Ridge was established in 1942 as a production site for the Manhattan Project—the massive American, British, and Canadian operation that developed the atomic bomb. Being the site of Oak Ridge National Laboratory and Y-12 National Security Complex, scientific and technological development still plays a crucial role in the city's economy and culture in general.[14] In 2016, the element tennessine was named for Tennessee, in recognition of the role played by Oak Ridge and other institutions in the state in its discovery.[15]
The earliest substantial occupation of the Oak Ridge area occurred during the Woodland period (c. 1000 BC – 1000), although artifacts dating to the Paleo-Indian period have been found throughout the Clinch River valley.[16] Two Woodland mound sites—the Crawford Farm Mounds and the Freels Farm Mounds—were uncovered in the 1930s as part of the Norris Basin salvage excavations. Both sites were just southeast of the former Scarboro community.[17] The Bull Bluff site, which was occupied during the Woodland and Mississippian (c. 1000–1600) periods, was uncovered in the 1960s in anticipation of the construction of Melton Hill Dam.[18] Bull Bluff is a cliff immediately southeast of Haw Ridge, opposite Melton Hill Park. The Oak Ridge area was largely uninhabited when Euro-American explorers and settlers arrived in the late 18th century, although the Cherokee claimed the land as part of their hunting grounds.
During the early 19th century, several rural farming communities developed in the Oak Ridge area, namely Edgemoor and Elza in the northeast, East Fork and Wheat in the southwest, Robertsville in the west, and Bethel and Scarboro in the southeast. The European-American settlers who founded these communities arrived in the late 1790s after the American Revolutionary War and after the Cherokee signed the Treaty of Holston, ceding what is now Anderson County to the United States.
A popular legend holds that John Hendrix (1865-1915), a largely unknown local man, predicted the creation of the city of Oak Ridge around 40 years before construction on the project began. Hendrix lacked any formal education and was a simple logger for much of his life. Following the death of his youngest daughter, Ethel, to diphtheria, and the subsequent departure of his wife and three remaining children, Hendrix began hearing voices in his head. These voices urged him to stay in the woods and pray for guidance for 40 days and 40 nights, which Hendrix proceeded to do. As the story is told, following these 40 days spent in rugged isolation, Hendrix began seeing visions of the future, and he sought to spread his prophetic message to any who would listen.[19] According to published accounts,[20] one vision that he described repeatedly was a description of the city and production facilities built 28 years after his death, during World War II.
The version recalled by neighbors and relatives reported:
In the woods, as I lay on the ground and looked up into the sky, there came to me a voice as loud and as sharp as thunder. The voice told me to sleep with my head on the ground for 40 nights and I would be shown visions of what the future holds for this land.... And I tell you, Bear Creek Valley someday will be filled with great buildings and factories, and they will help toward winning the greatest war that ever will be. And there will be a city on Black Oak Ridge and the center of authority will be on a spot middle-way between Sevier Tadlock's farm and Joe Pyatt's Place. A railroad spur will branch off the main L&N line, run down toward Robertsville and then branch off and turn toward Scarborough. Big engines will dig big ditches, and thousands of people will be running to and fro. They will be building things, and there will be great noise and confusion and the earth will shake. I've seen it. It's coming.[20]
Hendrix, in light of his tales of prophetic visions, was considered insane by most and at one point was institutionalized. His grave lies in an area of Oak Ridge now known as the Hendrix Creek Subdivision. There are ongoing concerns over the preservation of his gravestone, as the man who owns the lot adjacent to the grave wishes to build a home there, while members of the Oak Ridge Heritage and Preservation Association are fighting to have a monument placed on the site of his grave.[19]
Manhattan Project
In 1942, the United States federal government chose the area as a site for developing materials for the Manhattan Project. Major General Leslie Groves, military head of the Manhattan Project, liked the area for several reasons. Its relatively low population made acquisition affordable, yet the area was accessible by highway and rail, and utilities such as water and electricity were readily available with the recent completion of Norris Dam. The project location was established within a 17-mile-long (27 km) valley. This feature was linear and partitioned by several ridges, providing natural protection against the spread of disasters at the four major industrial plants—so the plants would not blow up "like firecrackers on a string".[21]
In October 1942, the United States Army Corps of Engineers began acquiring more than 60,000 acres (24,000 ha) in the Oak Ridge area for the United States' Manhattan Project. Due to the urgency and secrecy of the Manhattan Project, the Corps' "declaration of taking" was swift and final. Many residents came home to find eviction notices tacked to their doors. Others found out when their children came home from school with a message from the principal: Senator McKellar wants me to tell you to go home and tell your parents you are going to have to find another place to live." There was no further explanation as to why. All the students were told was this: "The government is going to take your property for the war effort."[22]
By March 1943 the Corps had removed the area's earlier communities and established fences and checkpoints. Anderson County lost one-seventh of its land and $391,000 in annual property tax revenue. The manner by which the Oak Ridge area was acquired by the government created a tense, uneasy relationship between the Oak Ridge complex and the surrounding towns.[23] Although the area's original residents were allowed to be buried in existing cemeteries, every coffin was reportedly opened for inspection.[24] The Corps' Manhattan Engineer District (MED) managed the acquisition and clearing. The K-25, S-50, and Y-12 plants were each built in Oak Ridge to separate the fissile isotope uranium-235 from natural uranium, which consists almost entirely of the isotope uranium-238. During construction of the electromagnets required for the uranium separation process at the Y-12 site, a shortage of copper forced the MED to borrow 14,700 tons of silver bullion from the United States Treasury as a copper substitute in wire for the electromagnet coils.[25] The X-10 site, now the site of Oak Ridge National Laboratory, was established as a pilot plant for production of plutonium using the Graphite Reactor.
When the Tennessee Governor Prentice Cooper was officially handed the July 1943 presidential proclamation by a junior officer (a lieutenant)—making Oak Ridge a military district not subject to state control—he tore it up and refused to see the Manhattan Project engineer, Lieutenant Colonel James C. Marshall. The new district engineer, Lieutenant Colonel Kenneth Nichols, had to placate him.[26][27] Cooper came to see the project (except for the production facilities under construction) on November 3, 1943; and he appreciated the bourbon-laced punch served (although Anderson County was "dry").[28]
House and dormitory accommodations at the Clinton Engineer Works (CEW) in Oak Ridge and Hanford Engineer Works in Washington were basic, with coal rather than oil or electric furnaces. But they were of a higher standard than Groves wanted and were better than at Los Alamos.[29] Medical care was provided by Army doctors and hospitals, with civilians paying $2.50 per month ($5 for families) to the medical insurance fund. [30]
Planned community
The location and low population helped keep the town a secret, though the settlement grew from 3,000 to 3,750 in 1942 to about 75,000 by 1945.[31][32] Because of the large number of workers recruited to the area for the Manhattan Project, the Army planned a town for project workers at the eastern end of the valley. The time required for the project's completion caused the Army to opt for a relatively permanent establishment rather than an enormous camp. The name "Oak Ridge" was chosen for the settlement in 1943 from suggestions submitted by project employees. The name evoked the settlement's location along Black Oak Ridge, and officials thought the rural-sounding name "held outside curiosity to a minimum".[33] The name was formally adopted in 1949.
The architectural and engineering firm Skidmore, Owings & Merrill was contracted to provide the layout for the town and house designs.[34] John O. Merrill moved to Tennessee to take charge of designing the secret buildings at Oak Ridge.[35] He directed the creation of a town,[36] which soon had 300 miles (480 km) of roads, 55 miles (89 km) of railroad track, ten schools, seven theaters, 17 restaurants and cafeterias, and 13 supermarkets. A library with 9,400 books, a symphony orchestra, sporting facilities, church services for 17 denominations, and a Fuller Brush Company salesman served the new city and its 75,000 residents.[31] No airport was built, for security reasons.[24] Prefabricated modular homes, apartments, and dormitories, many made from cemesto (bonded cement and asbestos) panels, were quickly erected. Streets were laid out in the manner of a "planned community".
The original streets included several main east-to-west roads, namely the Oak Ridge Turnpike, Tennessee Avenue, Pennsylvania Avenue, Hillside Road, Robertsville Road, and Outer Drive. North-to-south oriented streets connecting these main roads were designated "avenues", and streets branching off from the avenues were designated "roads", "places", "lanes", or "circles". "Roads" connected two streets, while "lanes" and "places" were dead ends.[37] The names of the main avenues generally progressed alphabetically from east to west (e.g., Alabama Avenue in the east, Vermont Avenue in the west), and the names of the smaller streets began with the same letter as the main avenue from which they started (e.g., streets connected to Florida Avenue began with "F").
The dramatic population increase, and the secret nature of the project, meant chronic shortages of housing and supplies during the war years. The town was administered by Turner Construction Company through a subsidiary named the Roane-Anderson Company.[24] For most residents, however, their "landlord" was known as "MSI" (Management Services, Inc.). All workers wore badges. The town was surrounded by guard towers and a fence with seven gates.
Segregation and desegregation
Oak Ridge was developed by the federal government as a segregated community, required by the Southern bloc of Democrats in Congress to authorize funding for the project. Due to generally holding lower-ranked jobs, their assigned dwellings were predominantly government-built "hutments" (one-room shacks) located very close to the Y-12 plant, in the one residential area designated as colored. Nichols, the MED District Engineer, was told by the main construction contractor for the K-25 plant that the black construction labor force had a large turnover rate, so Nichols gave permission to set up a separate black women's camp. When Groves visited the plant with K. T. Keller of Chrysler, Keller saw twelve Black women sweeping the 30-foot wide alley between the production units, and said "Nichols, don't you know there is a machine made to sweep a concrete floor like this?" Nichols replied "Sure I do, but these gals can do more than one of those machines". The men now had an opportunity to "fracas" on Saturday night, and labor turnover had reduced.[38]
During the war, plans were made for a colored neighborhood of houses equal in quality to those provided for whites, but it was not implemented because of limited resources. After the war, all hutments were dismantled, and a colored neighborhood of permanent houses was developed in the Gamble Valley area of Oak Ridge, which during wartime had been occupied by a white trailer community.
Oak Ridge elementary education prior to 1954 was segregated; it was legally part of the Anderson County system though built and operated primarily with federal funds.[39] Black children could attend only the Scarboro Elementary School. Oak Ridge High School was closed to black students, who had to be bused to Knoxville for an education. Starting in 1950, Scarboro High School was established at Scarboro Elementary School to offer classes for African-American students.[citation needed] In 1955, 85 young Black students from the Scarboro community were the first to enter all-white classes in Oak Ridge High School and Robertsville Junior High School (now Robertsville Middle School).[40] In 2023, on the 68th anniversary, a Scarboro 85 Monument was erected in Oak Ridge.[41]
Robertsville Junior High School, serving the west half of Oak Ridge, was desegregated at the same time as the high school. Elementary schools in other parts of the city and Jefferson Junior High School, serving the east half of the city, were desegregated slowly as African-American families moved into housing outside of Gamble Valley. In 1967 Scarboro Elementary School was closed, and African-American students from Gamble Valley were bused to other schools around the city.[citation needed]
The nearby high school in Clinton was desegregated in the fall of 1956. On October 5, 1958, it was bombed and closed while being rebuilt. Oak Ridge provided space at a recently vacated elementary school building (the original Linden Elementary School) for the education of high school students from Clinton for two years while Clinton High School was being rebuilt.
Following the Brown decision, public accommodations in Oak Ridge were gradually integrated, which took several years. In 1955, the spring-fed Oak Ridge Municipal Outdoor Swimming Pool, which had been completed in June 1945, became integrated.[42] In the early 1960s, Oak Ridge briefly experienced protest picketing against racial segregation in public accommodations, notably outside a local cafeteria and a laundromat.[43]
Since World War II
Two years after World War II ended, Oak Ridge was shifted to civilian control, under the authority of the U.S. Atomic Energy Commission. The Roane Anderson Company administered community functions, including arranging housing and operating buses, under a government contract.[44] In 1959 the town was incorporated. The community adopted a city manager and City Council form of government rather than direct federal control.
The S-50 liquid thermal diffusion plant was demolished soon after the war. K-25, where uranium was enriched by the gaseous diffusion process until 1985, was demolished in 2013–15. Two of the four major facilities created for the wartime bomb production remain standing:
- Y-12, originally used for electromagnetic separation of uranium, is used for nuclear weapons processing and materials storage.
- X-10, site of a graphite test reactor, is now Oak Ridge National Laboratory (ORNL).
The Department of Energy (DOE) runs ORNL, a nuclear and high-tech research establishment. In 1983, the DOE declassified a report showing that significant amounts of mercury had been released from the Oak Ridge Reservation into the East Fork Poplar Creek between 1950 and 1977. A federal court ordered the DOE to bring the Oak Ridge Reservation into compliance with federal and state environmental regulations.[45] In June 2018 IBM and ORNL unveiled Summit, the "world's fastest supercomputer", claimed to be more than twice as powerful as the previous world leader, with a peak performance of 200,000 trillion calculations per second.
Oak Ridge's scientific heritage is curated in the American Museum of Science and Energy. Its role in the Manhattan Project is preserved in the Manhattan Project National Historical Park (along with sites in Hanford, Washington and Los Alamos, New Mexico), run cooperatively by the National Park Service and the Department of Energy. A bus tour and several virtual tours are available for the public.[46]
Economic development
In 2003, the city extended its borders west beyond the Clinch River boundary for the annexation of the master planned community, the Preserve at Oak Ridge, paving the way for economic growth into the 21st century.[47] In January 2020, the city council of Oak Ridge approved the "Wilson Street Corridor" project plan, intended to develop and construct a downtown area in the city situated along Wilson Street. The plan consists of a mixed-use development of retail, residential usage, and restaurants with a primary focus of multi-story residential space.[48][49]
Immediately northeast of Oak Ridge, the southwestward-flowing Clinch River bends sharply to the southeast for roughly 6 miles (10 km) toward Solway, where it turns again to the southwest. After flowing for approximately 17 miles (27 km), the river bends sharply to the northwest at Copper Ridge, and continues in this direction for nearly 7 miles (11 km). At the K-25 plant, the Clinch turns southwest again and flows for another 11 miles (18 km) to its mouth along the Tennessee River at Kingston. This series of bends creates a half-rectangle formation—surrounded by water on the northeast, east, and southwest—in which Oak Ridge is situated.
The Oak Ridge area is striated by five ridges that run roughly parallel to one another in a northeast-to-southwest direction. In order from west-to-east, the five ridges are Blackoak Ridge (which connects the Elza and K-25 bends of the Clinch and thus "walls off" the half-rectangle), East Fork Ridge, Pine Ridge, Chestnut Ridge, and Haw Ridge. The five ridges are divided by four valleys: East Fork Valley (between Blackoak Ridge and East Fork Ridge), Gamble Valley (between East Fork Ridge and Pine Ridge), Bear Creek Valley (between Pine Ridge and Chestnut Ridge), and Bethel Valley (between Chestnut and Haw). These ridges and valleys are part of the Ridge-and-Valley Appalachians physiographic province. The main section of the city is located in the northeast, where East Fork and Pine Ridge give way to low, scattered hills. Many of the city's residences are located along the relatively steep northeastern slope of Blackoak Ridge.
The completion of Melton Hill Dam (along the Clinch near Copper Ridge) in 1963 created Melton Hill Lake, which borders the city on the northeast and east. The lakefront on the east side of the city is a popular recreation area, with bicycling trails and picnic areas lining the shore. The lake is well known as a venue for rowing competitions. Watts Bar Lake, an impoundment of the Tennessee River which covers the lower 23 miles (37 km) of the Clinch, borders Oak Ridge to the south and southwest.
According to the United States Census Bureau, the city has an area of 90.0 square miles (233.0 km2), of which 85.3 square miles (220.8 km2) is land and 4.7 square miles (12.2 km2), or 5.25%, is water.[50] The highest point is Melton Hill (35.90962°N 84.30525°W) on the DOE reservation, at elevation 1,356 feet (413 m).
Climate
Like much of the rest of the state, Oak Ridge has a humid subtropical climate (Cfa in the Köppen climate classification); it is part of USDA hardiness zone 7a.[51] The normal monthly mean temperature ranges from 37.9 °F (3.3 °C) in January to 77.5 °F (25.3 °C) in July, while on average there are 4.3 days where the temperature stays at or below freezing and 39 days with a high at or above 90 °F (32 °C) per year.[52][53] The all-time record low is −17 °F (−27 °C), set on January 21, 1985, while the all-time record high is 105 °F (41 °C), set on June 30, 2012, and July 28, 1952.[52] However, temperatures reaching either 0 °F (−18 °C) or 100 °F (38 °C) are uncommon, having last occurred February 5, 1996 (the date of the all-time record low for February) and July 1, 2012.[52]
Precipitation averages 59.70 inches (1,516 mm) annually and reaches a low during late summer. The rainiest calendar day on record is August 10, 1960, when 7.45 inches (189 mm) of rain fell; monthly precipitation has ranged from trace amounts in October 1963 to 19.27 inches (489 mm) in July 1967.[52]

Oak Ridge uses the council-manager government system, which was established in 1959 when the city was incorporated. It is governed by a seven-member city council composed of the mayor and six council members.[57]
Oak Ridge is represented in the Tennessee House of Representatives in the 33rd District in Anderson County, and the 32nd district in Roane County, by Representatives John Ragan and Kent Calfee respectively, both of whom are Republican.[58][59] In the Tennessee Senate, Oak Ridge is represented in the 5th district in Anderson County and the 12th district in Roane County, by Lieutenant Governor of Tennessee and Senator Randy McNally, and Senator Ken Yager respectively, both of whom are Republican.[60][61] Oak Ridge is represented in the United States House of Representatives by Republican Chuck Fleischmann of the 3rd congressional district.[62]
Unlike the rest of Anderson County, Oak Ridge, along with nearby Norris, has voted Democratic in recent federal elections, with the majority of the city having voted for Democratic presidential candidate Joe Biden in 2020.[63]
The federal government projects at Oak Ridge are reduced in size and scope but are still the city's principal economic activity and one of the largest employers in the Knoxville metropolitan area. The DOE owns the federal sites and maintains a major office in the city. Oak Ridge National Laboratory is the largest multipurpose lab in the DOE's National Laboratory system. It is home to the Spallation Neutron Source, a $1.4 billion project completed in 2006, and "Titan", one of the world's most powerful scientific supercomputers, which has peak performance of more than one quadrillion operations per second.
The Y-12 National Security Complex is a component of the U.S. nuclear weapons complex. The DOE's Environmental Management office is conducting an extensive program of decontamination and decommissioning, environmental cleanup, and waste management to remove or stabilize the hazardous residues remaining from decades of government production and research activities.
The DOE Office of Scientific and Technical Information disseminates government research and development information and operates the science.gov[64] website. The Oak Ridge Institute for Science and Education, operated by Oak Ridge Associated Universities, conducts research and education programs for the DOE, Department of Homeland Security, and other federal agencies. The Atmospheric Turbulence and Diffusion Division (ATDD), one of several field divisions of the National Oceanic and Atmospheric Administration Air Resources Laboratory, is also located in the city. ATDD began under AEC sponsorship in 1948 as a Weather Bureau research office providing meteorological information and expertise for the AEC. Currently its main function is to perform air quality-related research directed toward issues of national and global importance.
The nuclear industry continues to grow in Oak Ridge following the demolition of the K-25 site. Currently planned in Oak Ridge are a small modular reactor and/or a light-water reactor,[65] two nuclear fuel plants,[66][67] a nuclear research reactor,[68] a nuclear medicine plant,[69] and a uranium processing centrifuge. [70]
Boeing operated a manufacturing plant in the city beginning in the early 1980s which closed in 2007. IPIX, Remotec (now a subsidiary of Northrop Grumman), ZYP Coatings, and several other technology-based companies have been founded in Oak Ridge, including Greg LeMond's carbon fiber-manufacturing business, LeMond Composites. Several radioactive waste processing companies, including EnergySolutions, have operations in Oak Ridge.
The infrastructure that was new in the 1940s is aging. The once-isolated city is now incorporated into the Knoxville metropolitan area. Oak Ridge is now challenged to blend into the suburban orbit of Knoxville as its heritage as a "super secret" government installation subsides. Changing economic forces have led to continuing changes in the commercial sector. For example, the Oak Ridge City Center, a shopping center built in the 1950s and converted to an indoor shopping mall in the 1980s, sat largely empty in the years leading to its eventual partial demolition [71] and redevelopment.[72]
The city operates a preschool, four elementary schools enrolling kindergarten through grade 4, two middle schools enrolling grades 5 through 8, and one high school enrolling grades 9 through 12. The Oak Ridge school district was ranked number one in the state of Tennessee, and Oak Ridge High School was ranked the number three high school in the state of Tennessee, in the Niche 2017 Best School Districts.[73] Independent schools in the city include the Montessori School of Oak Ridge, St. Mary's School, and several preschools. The Oak Ridge Institute for Continued Learning offers a diverse array of educational opportunities for adults.[74]
Roane State Community College has its largest branch campus in Oak Ridge. Other higher education organizations present in the community but not offering classes locally include the Oak Ridge Institute for Science and Education, Oak Ridge Associated Universities, and the University of Tennessee Forestry Stations and Arboretum.
Oak Ridge is served by a daily newspaper, The Oak Ridger, and was for many years the home of AM radio station WATO.
Oak Ridge has a rowing venue on the Melton Hill Lake that hosts U.S. Rowing events such as the US Rowing Youth Summer National Championship [75] Oak Ridge has hosted cycling events for USA Cycling including the USA Cycling Individual Time Trial National Championships.[76]
A Minor League Baseball team called the Oak Ridge Pioneers played at the city's Ridgeview Park for one season in 1954.[77] The Oak Ridge Bombers played briefly in 1948 before relocating.[78]
