Biography
Gregory Breit — physicist with roots in the Russian Empire
Gregory Breit was a Ukrainian-born American physicist who made foundational contributions to nuclear physics and quantum electrodynamics. He co-discovered the ionosphere with Merle Tuve using radio waves, developed the Breit-Wigner formula for nuclear reactions, and worked on the Manhattan Project.
Russian Connection
Tracing the roots — Mykolaiv (Ukr)
Born in Mykolaiv, Ukraine (Russian Empire) in 1899, Breit emigrated to the United States and built one of the most distinguished careers in 20th-century American physics. His work spans experimental discovery, theoretical physics, and the most consequential weapons programme in history.
