George Gamow

The Big Bang theory was developed by Russian-born physicist George Gamow (1904-1968) and his colleagues in the 1950s. Gamow was an atomic physicist who helped explain how thermonuclear reactions power the stars. His knowledge of high-energy nuclear physics helped him explain how different particles formed in a "Hot Big Bang."
