NOTES ON GREGORY BREIT: Gregory Breit, born in Russia on July 14, 1899, was a physicist who worked on the early development of nuclear weapons and who calculated whether a chain reaction might set off a global explosion. He reported that theoretical calculations made it unlikely that a “runaway super” could set off a chain reaction but suggested tests with a new cyclotron at Oak Ridge National Laboratory in Tennessee that eventually supported his theory.
He came to the U.S. when he was 15 and earned his doctorate from Johns Hopkins in 1920. He was professor of physics at Yale from 1947 to 1968. Prior to that, he worked at New York University from 1929 to 1934 and University of Wisconsin from 1934 to 1947. He later went on to the State University of New York at Buffalo from 1968 to 1973.
In 1968, Breit received the national Medal of Science from President Johnson for his contributions to the first atom smashers and ordnance development. In 1964, he received the Franklin Medal for his work in nuclear physics.
After experiments in 1939 proved the concept of nuclear fission and validated its military potential, Breit suggested the voluntary censorship of the publication of uranium studies adhered to by scientists in World War II and participated in discussions that led President Franklin Roosevelt to declare an all-out press to produce atomic bombs in November 1941.
Breit made major contributions to the field of atomic and nuclear physics. He is remembered for introducing what is now known as the Breit interaction in atomic physics, and the Breit-Wigner formula in nuclear physics, and for contributing to the understanding of the nucleon-nucleon interaction in nuclear physics.
Breit died at the age of 82 on Sept. 13, 1981 in Salem, Ore.
