He was professor of theoretical physics at George Washington University (1934-56) and professor of physics at the University of Colorado (1956-68). Gamow made important contributions in a wide variety of fields, including radioactivity and cosmogony, as well as astrophysics and nuclear physics. He was one of the leading exponents of the theory of the evolutionary universe. He wrote many books for the general public, including The Birth and Death of the Sun (1940) and One, Two, Three ...
