Aiken in Aiken County, South Carolina — The American South (South Atlantic)
The Detection of the Neutrino, 1956 / The Nobel Prize In Physics, 1995
On August 27, 1956, at the Savannah River Plant (now Savannah River Site), Drs. Clyde L. Cowan, Jr. (1919-1974) and Frederick Reines (1918-1999) used P Reactor to detect the neutrino, a sub-atomic particle hypothesized in 1930 but unconfirmed until their experiment, one of the most significant in modern physics.
The Nobel Prize In Physics, 1995
In 1995 Dr. Frederick Reines was awarded the Nobel Prize in Physics for his and Dr. Clyde L. Cowan’s detection of the neutrino at the Savannah River Plant. The Nobel citation called their experiment “a pioneering contribution that opened the doors to the region of ‘impossible’ neutrino experiments.”

Regarding The Detection of the Neutrino, 1956 / The Nobel Prize In Physics, 1995. Aiken Standard
A crowd of more than 50 people gathered in front of the Greater Aiken Chamber of Commerce Friday morning to commemorate scientific history made in Aiken 54 years ago. Members of local government, county residents and Savannah River Site employees and their families kicked off the all-day celebration of the discovery of the neutrino, an elementary particle with no charge and nearly no mass first detected at SRS.
The discovery, made by a team led by Clyde Cowan and Frederick Reines, earned the only Nobel Prize for physics ever awarded in the state of South Carolina to date."Neutrinos are the closest thing to nothing that's still something," SRS Heritage Foundation Executive Director Walt Joseph said
Among the crowd on Friday morning were Marian Cowan Kriston and Elizabeth Cowan Riordon, daughters of the late Clyde Cowan, who returned to Aiken this week from Maryland and Ohio, respectively."The family is so excited, and we have such memories of Aiken. It is so wonderful that they've kept the history," said Marian, who was just over 1 year
Elizabeth, who was 11 years old when her father detected the neutrino at SRS, recalls the partnership between her father and Reines.
"Fred kept the math going, and Daddy - he liked the math, but he kept the equipment going," she said.
The historical marker, which now stands directly in front of the chamber building at 121 Richland Ave., was also unveiled during the ceremony. The plaque, a replica of the original plaque awarded by the U.S. Atomic Energy Commission which is now at the University of California-Irvine, was also officially unveiled at the ceremony.The celebration continued Friday afternoon with informative presentations at USCA's Etherredge Center. The crowd watched a video of the late Cowan discussing the experiments and research that led to the neutrino's detection, as well as presentations about neutrinos in particle astrophysics and neutrino research in using accelerators.
The evening concluded with a sit-down dinner at Newberry Hall and a speech by Dr. John Palms, distinguished president emeritus of the University of South Carolina.
The event was part of Aiken's 175th anniversary celebration.

1. Clyde Lorrain Cowan Jr, Wikipedia entry. Cowan joined the U.S. Army Chemical Warfare Service with the rank of Second Lieutenant when America joined World War II in 1941. In August 1942, he was transferred to Eisenhower's Eighth Air Force stationed in London, England. In 1943 he designed and built an experimental cleaning unit to be used in case of gas attack. In the following year, he joined the staff of the British Branch of the Radiation Laboratory of the Massachusetts Institute of Technology, which was located in Great Malvern, England. In 1945 he was a liaison officer with the Royal Air Force, working to expedite transmittal of technical information and equipment. He returned to the United States in 1945, and worked at Wright Patterson Air Force Base in Dayton, Ohio. He left active duty in 1946.
