Person: Lorentz, Hendrik Antoon
Hendrik Lorentz is best known for his work on electromagnetic radiation and the FitzGeraldLorentz contraction. He developed the mathematical theory of the electron.
Mathematical Profile (Excerpt):
 Lorentz refined Maxwell's electromagnetic theory in his doctoral thesis The theory of the reflection and refraction of light presented in 1875.
 After retiring from this chair, Lorentz was appointed director of research at the Teyler Institute, Haarlem.
 Before the existence of electrons was proved, Lorentz proposed that light waves were due to oscillations of an electric charge in the atom.
 Lorentz developed his mathematical theory of the electron for which he received the Nobel Prize in 1902.
 The Nobel prize was awarded jointly to Lorentz and Pieter Zeeman, a student of Lorentz.
 Zeeman had verified experimentally Lorentz's theoretical work on atomic structure, demonstrating the effect of a strong magnetic field on the oscillations by measuring the change in the wavelength of the light produced.
 Lorentz is also famed for his work on the FitzGeraldLorentz contraction, which is a contraction in the length of an object at relativistic speeds.
 Lorentz transformations, which he introduced in 1904, form the basis of Einstein's special theory of relativity.
 Lorentz was chairman of the first Solvay Conference held in Brussels in the autumn of 1911.
 However Lorentz never fully accepted quantum theory and always hoped that it would be possible to incorporate it back into the classical approach.
 Lorentz received a great many honours for his outstanding work.
Born 18 July 1853, Arnhem, Netherlands. Died 4 February 1928, Haarlem, Netherlands.
