Ernest, Lord Rutherford

Ernest Rutherford (1871-1937), Baron Rutherford of Nelson, was born in Nelson, New Zealand. In 1895 he came to England to be a research student under J.J. Thomson at the Cavendish Laboratory, Cambridge. His first professorial appointment was at McGill University in Montreal, 1898-1907, where he and Frederick Soddy advanced the transformation theory, the interpretation of the phenomenon of radioactivity.

Rutherford returned to England to work at the University of Manchester, 1907-1919, where he succeeded Arthur Schuster as director of the physical laboratory. At the university Hans Geiger, a staff member, and Ernest Marsden, a student, performed the alpha particle scattering experiments that led Rutherford to formulate the concept of the nuclear atom in 1911. Shortly before leaving Manchester in 1919 for Cambridge, where he succeeded his own teacher, J.J. Thomson, Rutherford announced a major discovery, the artificial transformation of one element into another. This work was continued in the Cavendish Laboratory, primarily with Chadwick's aid. From 1925 to 1930 Rutherford was also President of the Royal Society.
