Biography
Frederick Reines (March 16, 1918 – August 26, 1998) was an American physicist known for co-detecting the neutrino, a fundamental particle that had been predicted but never seen before. Born in Paterson, New Jersey, Reines studied at Union Hill High School, Stevens Institute of Technology, and New York University. His significant work in particle physics won him the 1995 Nobel Prize in Physics, which he shared with Martin Perl, highlighting his key role in discovering and studying an elementary particle.
Reines joined the Manhattan Project's Los Alamos Laboratory in 1944, working in the Theoretical Division under Richard Feynman. By 1946, he had become a group leader and took part in many nuclear tests. His work with nuclear weapons research peaked when he directed the Operation Greenhouse test series in the Pacific in 1951. This experience with nuclear reactors and radiation detection was crucial for his later neutrino research.
In the early 1950s, Reines teamed up with Clyde Cowan to solve one of physics' biggest challenges: detecting the elusive neutrino. At the Hanford and Savannah River Sites, they created advanced tools and methods to find evidence of these nearly massless particles that interact weakly with matter. Their efforts succeeded in June 1956 when they detected neutrinos for the first time, confirming a particle that Wolfgang Pauli had suggested in 1930 but thought might never be observed directly.
After this major discovery, Reines focused much of his career on studying neutrino properties and interactions. His research went beyond lab detection to cosmic events, including finding atmospheric neutrinos from cosmic rays. In 1987, his work helped detect neutrinos from Supernova SN1987A, which played a role in starting the field of neutrino astronomy. Throughout his career, Reines received many honors, such as the National Medal of Science in 1983, the J. Robert Oppenheimer Memorial Prize in 1981, the Franklin Medal in 1992, and the Panofsky Prize in 1992. He passed away in Orange, California, on August 26, 1998, having greatly advanced our understanding of fundamental particles and their importance in the universe.
Before Fame
Frederick Reines grew up in the early 20th century when physics was changing with the development of quantum mechanics and nuclear physics. As a young Eagle Scout in New Jersey, he showed the dedication and methodical approach that would later define his scientific work. He studied at Stevens Institute of Technology and New York University during a time when American universities became important centers for physics research, especially as European scientists moved to the U.S. in the 1930s.
World War II opened up new opportunities for young physicists to work on national defense projects. Reines joined the Manhattan Project in 1944, putting him at the heart of the most important scientific project of the time. He worked with future Nobel laureates and learned nuclear physics techniques that would directly influence his later work on neutrino detection experiments.
Key Achievements
- Co-detected the neutrino with Clyde Cowan in 1956, confirming a fundamental particle predicted 26 years earlier
- Served as director of Operation Greenhouse nuclear test series in the Pacific in 1951

- Won the Nobel Prize in Physics in 1995 for neutrino detection work
- Established methods and equipment that enabled decades of subsequent neutrino research
Did You Know?
- 01.Reines and Cowan originally planned to detect neutrinos using an atomic bomb explosion but later switched to using nuclear reactors as a more practical neutrino source
- 02.He was the only scientist to achieve Eagle Scout rank and later win the Nobel Prize in Physics
- 03.The first telegram announcing the successful neutrino detection was sent to Wolfgang Pauli with the message 'We are happy to inform you that we have definitely detected neutrinos'
- 04.Reines initially studied mechanical engineering at Stevens Institute before switching to theoretical physics
- 05.His neutrino detection apparatus was nicknamed 'Project Poltergeist' because neutrinos were like ghosts that could pass through matter undetected
