Walton, Rutherford and Cockroft. Portrait of (from left to right) Ernest Walton (1903-1995), Ernest Rutherford (1871-1937) and John Cockroft (1897-1967). Cockroft and Walton shared the 1951 Nobel Prize for Physics for their work on splitting the atomic nucleus. Rutherford's early work on radioactivity at McGill University, Canada led to his 1908 Nobel Prize in Chemistry. His most famous work took place in 1909 at the University of Manchester, England. The Geiger-Marsden experiment fired helium ions (alpha particles) at thin gold foil. The resulting scattering pattern led to the Rutherford model of the atom. From 1919 to his death, Rutherford directed the Cavendish Laboratory. Photographed outside Cavendish Laboratory, Cambridge University, UK, in 1932.
