Sir George Paget Thomson, FRS[1] (; 3 May 1892 – 10 September 1975) was an English physicist and Nobel laureate in physics recognised for his discovery with Clinton Davisson of the wave properties of the electron by electron diffraction.[2][3]

Education and early life

Thomson was born in The Perse School, Cambridge before going on to read mathematics and physics at Trinity College, Cambridge, until the outbreak of World War I in 1914, when he was commissioned into the Queen's Royal West Surrey Regiment. After brief service in France, he worked on aerodynamics at Farnborough and elsewhere. He resigned his commission as a Captain in 1920.

Career

After briefly serving in the Nobel Prize for Physics in 1937 for his work in Aberdeen in discovering the wave-like properties of the electron. The prize was shared with Clinton Joseph Davisson who had made the same discovery independently. Whereas his father had seen the electron as a particle (and won his Nobel Prize in the process), Thomson demonstrated that it could be diffracted like a wave, a discovery proving the principle of wave-particle duality which had first been posited by Louis-Victor de Broglie in the 1920s as what is often dubbed the de Broglie hypothesis.

Between 1929–1930 Thomson was a Non–Resident Lecturer at Cornell University, Ithaca, New York.[2] In 1930 he was appointed Professor at Imperial College London in the chair of the late Hugh Longbourne Callendar. In the late 1930s and during the Second World War Thomson specialised in nuclear physics, concentrating on practical military applications. In particular Thomson was the chairman of the crucial MAUD Committee in 1940–1941 that concluded that an atomic bomb was feasible. In later life he continued this work on nuclear energy but also wrote works on aerodynamics and the value of science in society.

Thomson stayed at Imperial College until 1952, when he became Master of Leckhampton campus.

Awards and honours

In addition to winning the Nobel Prize in Physics, Thomson was knighted in 1943. He gave the address "Two aspects of science" as president of the British Association for 1959–1960.[4]

Personal life

In 1924, Thomson married Kathleen Buchanan Smith, daughter of the Very Rev. Sir George Adam Smith. They had four children, two sons and two daughters. Kathleen died in 1941.
