Fowler, WilliamAlfred (1911–95)Americanphysicist and astrophysicist. In 1938, H. A.Bethe had proposed the proton–proton reaction as a source of energy in stars. Fowler demonstrated theoretically that the process was indeed possible. In the 1950s, he collaborated with G. R. and E. M.Burbidge and F.Hoyle on a theory of energy generation and nucleosynthesis in stars (known as the B²FH theory). Further theoretical work with Hoyle in the late 1960s showed that a hot Big Bang would produce the observed amount of helium in the Universe. He and S.Chandrasekhar shared the 1983 Nobel Prize in Physics.

Fowler, William Alfred

World Encyclopedia | 2005 | Copyright

Fowler, William Alfred (1911–95) US physicist and astrophysicist best known for his explanation of how chemical elements are built up (from heavier to lighter) within stars as they evolve. He developed these ideas (published 1957) while working with three British astronomers: Fred Hoyle, and Geoffrey and Margaret Burbidge. In 1983, he shared the Nobel Prize in physics with Subrahmanyan Chandrasekhar.
