September 10, 1975 - Death of George Paget Thomson, Nobel Prize for his studies on the diffraction of electrons in crystals and the demonstration of their wave properties

The only son of the well-known Sir Joseph John Thomson, in 922 he became a professor at the University of Aberdeen, where he carried out experiments that revealed the diffraction of a beam of electrons when passing through a crystalline substance, thus confirming the theories of Louis de Broglie, about wave-particle duality.

This new theoretical conception of the nature of radiation made it possible to confirm Einstein's previous hypotheses and explain the Compton effect (named after its discoverer, Arthur Compton), which was lacking in the wave theory of light.

In 1937, he shared the Nobel Prize in Physics with the American physicist Clinton J. Davisson, for their work related to the diffraction of electrons in crystals and the demonstration of their wave properties.

In 1943, he was awarded the title of Sir and in 1946 he served as advisor to the British delegation to the United Nations Security Council and the Atomic Energy Commission.
