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.
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.
Norris Edwin Bradbury, was an American physicist who served as director of the Los Alamos National Laboratory for 25 years from 1945 to 1970. He succeeded Robert Oppenheimer, who personally chose Bradbury for the position of director after working closely with him on the Manhattan Project during World War II. Bradbury was in charge of the final assembly of "the Gadget", detonated in July 1945 for the Trinity test.
George Arthur Cowan was an American physical chemist, a businessman and philanthropist.
Siegfried S. Hecker is an American metallurgist and nuclear scientist. He served as Director of the Los Alamos National Laboratory from 1986 to 1997 and is now affiliated with Stanford University, where he is research professor emeritus in the Department of Management Science and Engineering in the School of Engineering, and senior fellow emeritus at the Freeman Spogli Institute for International Studies. During this time, he was also elected a member of the National Academy of Engineering (1988) for outstanding research on plutonium and the forming of materials, and for leadership in developing energy and weapons systems.
Darleane Christian Hoffman is an American nuclear chemist who was among the researchers who confirmed the existence of seaborgium, element 106. She is a faculty senior scientist in the Nuclear Science Division of Lawrence Berkeley National Laboratory and a professor in the graduate school at UC Berkeley. In acknowledgment of her many achievements, Discover magazine recognized her in 2002 as one of the 50 most important women in science.

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 13,200 as of 2020. 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.
Wick C. Haxton is an American theoretical nuclear physicist and astrophysicist. He is a professor of physics at the University of California, Berkeley and senior faculty scientist at Lawrence Berkeley National Laboratory. He was appointed a co-editor of the journal Annual Review of Nuclear and Particle Science as of 2023.
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.
Joseph Oakland Hirschfelder was an American physicist who participated in the Manhattan Project and in the creation of the nuclear bomb.
John M. "Jack" Carpenter was an American nuclear engineer known as the originator of the technique for utilizing accelerator-induced intense pulses of neutrons for research and developing the first spallation slow neutron source based on a proton synchrotron, the Intense Pulsed Neutron Source (IPNS). He died on 10 March 2020.
Robert Graham Hamish Robertson is a Canadian–American experimental physicist, specializing in neutrino physics. He is a Professor Emeritus at the University of Washington, where he was formerly the director of the University of Washington's Center for Experimental Nuclear Physics and Astrophysics.
Terry C. Wallace Jr. is an American geophysicist. He was the 11th director of Los Alamos National Laboratory and the president of Los Alamos National Security, LLC. He became director on January 1, 2018, succeeding Charles F. McMillan.
Thomas Mason is a Canadian-American condensed-matter physicist who serves as the director of Los Alamos National Laboratory. Prior to this appointment, he had been an executive at Battelle Memorial Institute from 2017 to 2018, and the director of Oak Ridge National Laboratory from 2007 to 2017. Mason moved to Oak Ridge in 1998 at the start of construction of the Spallation Neutron Source which he led from 2001 until project completion in 2006.
Dana Dattelbaum is an American physicist and scientist at Los Alamos National Laboratory. She leads NNSA’s Dynamic Materials Properties portfolio at LANL, which provides experimental data, platforms and diagnostics for materials behaviors relevant to nuclear weapons performance, ranging from plutonium to high explosives.
Harshini Mukundan is an Indian-American microbiologist. She is a Fellow of the American Association for the Advancement of Science.
Geoffrey L. Greene is an American neutron physicist. Greene received his bachelor's degree from Swarthmore College in 1971 and his doctorate from Harvard University in 1974 with Norman Ramsey, a Nobel laureate in physics. There he worked on low-energy (cold) neutrons, which were then first available in intense beams. As a post-doctoral fellow he was at the Rutherford Appleton Laboratory and the Institut Laue-Langevin. He was an assistant professor at Yale University and then at the National Institute of Standards and Technology (NIST). He has held various management positions at Los Alamos National Laboratory. Since 2002, he is a professor at the University of Tennessee and Oak Ridge National Laboratory.
Jen-Chieh Peng is an experimental nuclear physicist at the University of Illinois at Urbana–Champaign.
Robert Everett Ecke is an American experimental physicist who is a laboratory fellow and director emeritus of the Center for Nonlinear Studies (CNLS) at Los Alamos National Laboratory and Affiliate Professor of Physics at the University of Washington. His research has included chaotic nonlinear dynamics, pattern formation, rotating Rayleigh-Bénard convection, two-dimensional turbulence, granular materials, and stratified flows. He is a Fellow of the American Physical Society (APS) and of the American Association for the Advancement of Science (AAAS), was chair of the APS Topical Group on Statistical and Nonlinear Physics, served in numerous roles in the APS Division of Fluid Dynamics, and was the Secretary of the Physics Section of the AAAS.
