One of Thomson's students was Ernest Rutherford, who later succeeded him as Cavendish Professor of Physics. Six of Thomson's research assistants and junior colleagues (Charles Glover Barkla, Niels Bohr, Max Born, William Henry Bragg, Owen Willans Richardson and Charles Thomson Rees Wilson) won Nobel Prizes in physics, and two (Francis William Aston and Ernest Rutherford) won Nobel prizes in chemistry. Thomson's son (George Paget Thomson) also won the 1937 Nobel Prize in physics.
