in Aberdeen by G P Thomson (1892-1975), the son of J J Thomson (1856-1940) who identified the electron. Working in the same field, G P Thomson observed diffraction of electrons passing through thin gold foil, recorded on photographic plates as concentric rings of varying intensity about the incident beam. This supported the idea of de Brogle that particles had wave-like properties. In 1937, G P Thomson received the Nobel Prize for this work, jointly with the American physicist C J Davisson (1881-1958) who also observed electron diffraction using nickel crystals.
