The most significant work was done by Eugene Wigner (who came from Hungary), GeorgeGamow (Russia), Felix Bloch (Switzerland), Hans Bethe (Germany), Edward Teller (Hungary), and Victor Weisskopf (Austria).
Edward Teller and GeorgeGamow had set up a series of meetings among astronomers and theoretical physicists who shared the goal of exploring the key energy issues of the period.
In 1948 GeorgeGamow, a fellow pioneer of nuclear physics, added Mr Bethe's name without asking to a paper that explained how chemical elements had been made in the Big Bang.
