    • Nobelprijs natuurkunde (1902)

      In Gens Nostra 27(9) september 1972, pp.265-266, beschrijft A.A. van de Craats te Drempt het gemeenschappelijk voorouderpaar van Kamerlingh Onnes en Lorentz, te weten Lubbert Braakman en Willemken Jans, en hun tweelingdochters Janna en Geertruit, gedoopt Velp 09.12.1700.

      Attended primary school in Arnhem until he was 13 years of age when he entered the new High School there. He entered the University of Leiden in 1870 but, in 1872, he returned to Arnhem to take up teaching evening classes. He worked for his doctorate while holding the teaching post.
      Lorentz refined Maxwell's electromagnetic theory in his doctoral thesis The theory of the reflection and refraction of light presented in 1875. He was appointed professor of mathematical physics at Leiden University in 1878. He remained in this post until he retired in 1912 when Ehrenfest was appointed to his chair. After retiring from this chair, Lorentz was appointed director of research at the Teyler Institute, Haarlem. He retained an honorary position at Leiden, where he continued to lecture.
      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 FitzGerald- Lorentz 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. They describe the increase of mass, the shortening of length, and the time dilation of a body moving at speeds close to the velocity of light.
      Lorentz was chairman of the first Solvay Conference held in Brussels in the autumn of 1911. This conference looked at the problems of having two approaches, namely the classical physics and quantum theory. However Lorentz never fully accepted quantum theory and always hoped that it would be possible to incorporate it back into the classical approach. He said in his presidential address at the opening ceremony of the conference:-
      In this stage of affairs there appeared to us like a wonderful ray of light the beautiful hypothesis of energy elements which was first expounded by Planck and then extended by Einstein and Nernst, and others to many phenomena. It has opened for us unexpected vistas, even those, who consider it with a certain suspicion, must admit its importance and fruitfulness.

      In [6] O W Richardson describes Lorentz as:-
      ... a man of remarkable intellectual powers ... . Although steeped in his own investigation of the moment, he always seemed to have in his immediate grasp its ramifications into every corner the universe. ... The singular clearness of his writings provides a striking reflection of his wonderful powers in this respect. .... He possessed and successfully employed the mental vivacity which is necessary to follow the interplay of discussion, the insight which is required to extract those statements which illuminate the real difficulties, and the wisdom to lead the discussion among fruitful channels, and he did this so skillfully taught the process was hardly perceptible.

      Lorentz received a great many honours for his outstanding work. He was elected a Fellow of the Royal Society in 1905. The Society awarded him their Rumford Medal in 1908 and their Copley Medal in 1918.

      The respect that Lorentz was held in in The Netherlands is seen in Richardson's description of his funeral [6]:-
      The funeral took place at Haarlem at noon on Friday, 10 February. At the stroke of twelve the State telegraph and telephone services of Holland were suspended for three minutes as a revered tribute to the greatest man Holland has produced in our time. It was attended by many colleagues and distinguished physicists from foreign countries. The President, Sir Ernest Rutherford, represented the Royal Society and made an appreciative oration by the graveside.
