George Gamow (March 4 1904 – August 19, 1968), born Georgiy Antonovich Gamov (Russian: Георгий Антонович Гамов), was a theoretical physicist and cosmologist — notably an early advocate and developer of Lemaître's Big Bang theory. He discovered a theoretical explanation of alpha decay via quantum tunneling, and worked on radioactive decay of the atomic nucleus, star formation, stellar nucleosynthesis and Big Bang nucleosynthesis (which he collectively called nucleocosmogenesis), and molecular genetics.
In his middle and late career, Gamow focussed more on teaching, and became well known as an author of popular books on science, including One Two Three ... Infinity, and the Mr. Tompkins ... series of books (1939–1967). Some of his books are still in print more than a half-century after their original publication, and have become classic but still-relevant introductions to fundamental principles of mathematics and science.
