Heike Kamerlingh Onnes Heike Kamerlingh Onnes Professor Heike Kamerlingh Onnes FRSFor HFRSE FCS ( (); 21 September 1853 – 21 February 1926) was a Dutch physicist and Nobel laureate. He exploited the Hampson–Linde cycle to investigate how materials behave when cooled to nearly absolute zero and later to liquefy helium for the first time, in 1908. He was also the discoverer of superconductivity in 1911. Kamerlingh Onnes was born in Groningen, Netherlands. His father, Harm Kamerlingh Onnes, was a brickworks owner. His mother was Anna Gerdina Coers of Arnhem. In 1870, Kamerlingh Onnes attended the University of Groningen. He studied under Robert Bunsen
Harm Kamerlingh Onnes Lorentz as a subject. One of these stained-glass windows contained a portrait of Hendrik Lorentz and formulas devised by him that describe the behavior of electrons. Other stained-glass windows show the instruments to measure the splitting of spectral lines of atoms under the influence of a magnetic field is measured, the so-called Zeeman effect. He also made portraits of the physicists Albert Einstein and Paul Ehrenfest. Harm Kamerlingh Onnes characterized his artistic work with the phrase "just messing around". In 1953 Kamerlingh Onnes with Bert Nienhuis Piet Wiegman, Dirk Hubers and Frans Wildenhain, took part of the exhibition "five contemporary
