Los Alamos National Laboratory is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions.
Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. Concerns about whether the complex Fat Man design would work led to a decision to conduct the first nuclear test. The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne.
Cimarron is a village in Colfax County, New Mexico, United States, which sits on the eastern slopes of the Sangre de Cristo Mountains. The population was 792 at the 2020 census, making it the fourth most populous municipality in Colfax County.
Val Logsdon Fitch was an American nuclear physicist who, with co-researcher James Cronin, was awarded the 1980 Nobel Prize in Physics for a 1964 experiment using the Alternating Gradient Synchrotron at Brookhaven National Laboratory that proved that certain subatomic reactions do not adhere to fundamental symmetry principles. Specifically, they proved, by examining the decay of K-mesons, that a reaction run in reverse does not retrace the path of the original reaction, which showed that the reactions of subatomic particles are not indifferent to time. Thus the phenomenon of CP violation was discovered. This demolished the faith that physicists had that natural laws were governed by symmetry.
William Sterling Parsons was an American naval officer who worked as an ordnance expert on the Manhattan Project during World War II. He is best known for being the weaponeer on the Enola Gay, the aircraft which dropped an atomic bomb on Hiroshima, Japan, in 1945. To avoid the possibility of a nuclear explosion if the aircraft crashed and burned on takeoff, he decided to arm the bomb in flight. While the aircraft was en route to Hiroshima, Parsons climbed into the cramped and dark bomb bay, and inserted the powder charge and detonator. He was awarded the Silver Star for his part in the mission.
Sandia Base was the principal nuclear weapons installation of the United States Department of Defense from 1946 to 1971. It was located on the southeastern edge of Albuquerque, New Mexico. For 25 years, the top-secret Sandia Base and its subsidiary installation, Manzano Base, carried on the atomic weapons research, development, design, testing, and training commenced by the Manhattan Project during World War II. Fabrication, assembly, and storage of nuclear weapons was also done at Sandia Base. The base played a key role in the United States nuclear deterrence capability during the Cold War. In 1971 it was merged into Kirtland Air Force Base.
James Leslie Tuck was a British physicist, working on the applications of explosives as part of the British delegation to Manhattan Project.
The Bradbury Science Museum is the chief public facility of Los Alamos National Laboratory, located at 1350 Central Avenue in Los Alamos, New Mexico, in the United States. It was founded in 1953, and was named for the Laboratory's second director (1945–1970), Norris E. Bradbury. Among the museum's early exhibits, artifacts and documents from World War II Manhattan Project were displayed upon declassification. Other exhibits include full-size models of the Little Boy and Fat Man atomic bombs. Admission is free.
Stirling Auchincloss Colgate was an American nuclear physicist at the Los Alamos National Laboratory and a professor emeritus of physics at the New Mexico Institute of Mining and Technology from 1965 to 1974, of which he also served its president.
John Gaw Meem IV was an American architect based in Santa Fe, New Mexico. He is best known for his instrumental role in the development and popularization of the Pueblo Revival Style and as a proponent of architectural Regionalism in the face of international modernism. Meem is regarded as one of the most important and influential architects to have worked in New Mexico.
John Davis Wirth was an American historian and academic who was the Gildred Professor of Latin American Studies at Stanford University. A specialist in economic history, he studied developmentalism, international trade, and the creation of the steel and petroleum industries. A deepening interest in environmentalism led to his appointment in 1994 by President Bill Clinton as one of the five members of the Joint Public Advisory Committee of the North American Commission for Environmental Cooperation.
The Los Alamos Historical Museum is housed in the historic Guest House, located next to Fuller Lodge, of Los Alamos Ranch School, which was General Leslie Groves's favorite place to stay during the Manhattan Project.
Los Alamos is a census-designated place in Los Alamos County, New Mexico, United States, that is recognized as one of the development and creation places of the atomic bomb—the primary objective of the Manhattan Project by Los Alamos National Laboratory during World War II. The town is located on four mesas of the Pajarito Plateau, and had a population of about 19,200 as of 2022. It is the county seat and one of two population centers in the county known as census-designated places (CDPs); the other is White Rock.
Harold Melvin Agnew was an American physicist, best known for having flown as a scientific observer on the Hiroshima bombing mission and, later, as the third director of the Los Alamos National Laboratory.
The Otowi Historic District is a 29-acre (0.12 km2) historic district in northern Santa Fe County, New Mexico, having four contributing buildings and three contributing structures including Otowi Suspension Bridge and was listed on the National Register of Historic Places in 1975.
The history of New Mexico during World War II is characterized by dramatic and lasting changes to its economy, society, and politics. The state played a central role in the American war effort, contributing a disproportionately high number of servicemen and natural resources; most famously, it hosted the sites where the world's first nuclear weapon was designed, developed, and tested.
A ranch school is a type of school used in rural areas of the Western United States.
Dorothy McKibbin worked on the Manhattan Project during World War II. She ran the project's office at 109 East Palace Avenue in Santa Fe, through which staff moving to the Los Alamos Laboratory had to pass through to obtain security credentials and directions to their new workplace. She was known as the "first lady of Los Alamos", and was often the first point of contact for new arrivals. She retired when the Santa Fe office closed in 1963.
The Los Alamos Laboratory, also known as Project Y, was a secret laboratory established by the Manhattan Project and operated by the University of California during World War II. Its mission was to design and build the first atomic bombs. Robert Oppenheimer was its first director, serving from 1943 to December 1945, when he was succeeded by Norris Bradbury. In order to enable scientists to freely discuss their work while preserving security, the laboratory was located on the isolated Pajarito Plateau in Northern New Mexico. The wartime laboratory occupied buildings that had once been part of the Los Alamos Ranch School.
Edith Warner (1893–1951), also known by the nickname "The Woman at Otowi Crossing", was an American tea room owner in Los Alamos, New Mexico, who is best known for serving various scientists and military officers working at the Los Alamos National Laboratory during the original creation of the atomic bomb as a part of the Manhattan Project. Warner's influence on the morale and overall attitude of the people there has been noted and written about by various journalists and historians, including several books about her life, a stage play, a photography exhibition, an opera, and a dance.
