Heike Kamerlingh Onnes (September 21, 1853 – February 21, 1926) was a Dutch physicist. His scientific career was spent exploring extremely cold refrigeration techniques and the associated phenomena.

Early years and professorship

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 and Gustav Kirchhoff at the University of Heidelberg from 1871 to 1873. Again at Groningen, he obtained his masters in 1878 and a doctorate in 1879. His thesis was "Nieuwe bewijzen voor de aswenteling der aarde" (tr. New proofs of the rotation of the earth). From 1878 to 1882 he was assistant to Johannes Bosscha , the director of the Polytechnic in Delft, for whom he substituted as lecturer in 1881 and 1882.

From 1882 to 1923 Kamerlingh Onnes served as professor of experimental physics at the University of Leiden. In 1904 he founded a very large cryogenics laboratory and invited other researchers to the location, which made him highly regarded in the scientific community. In 1908 He was the first physicist to liquify helium, using cryostats. Using the Joule-Thomson effect, he lowered the temperature to less than one degree above absolute zero, reaching 0.9 K. At the time this was the coldest temperature achieved on earth.

He was married to Maria Adriana Wilhelmina Elisabeth Bijleveld (m. 1887) and had a child named Albert.

Superconductivity

Kamerlingh Onnes conducted (in 1911) electrical analysis of pure metals (mercury, tin and lead) at very low temperatures. Some, such as William Thomson, believed that electrons flowing through a conductor would come to a complete halt. Others, including Kamerlingh Onnes, felt that a conductor's electrical resistance would steadily decrease and drop to nil. Ludwig Matthiessen (1830-1906) pointed out when the temperature decreases, the metal resistance decreases and then becomes constant with further decrease in temperature. At 4.2 kelvin the resistance was zero. The drop to zero was experimentally observed to be abrupt. Kamerlingh Onnes stated that the "Mercury has passed into a new state, which on account of its extraordinary electrical properties may be called the superconductive state". He published more articles about the phenomenon, initially referring to it as "supraconductivity" and, only later adopting the term "superconductivity".

Kamerlingh Onnes received widespread recognition for his work, including the 1913 Nobel Prize in Physics for (in the words of the committee) "his investigations on the properties of matter at low temperatures which led, inter alia, to the production of liquid helium".

Awards

  • Matteucci Medal (1910)
  • Rumford Medal (1912)
  • Nobel Prize for Physics (1913)

Death and afterwards

Kamerlingh Onnes died in Leiden. Some of the instruments he devised for his experiments can still be seen at the Boerhaave Museum in Leiden. The apparatus he used to first liquefy helium is on display in the lobby of the physics department at Leiden University, where the low temperature lab is also named in his honor. His student and successor as director of the lab Willem Hendrik Keesom was the first person who was able to solidify helium, in 1926.

The Onnes-effect referring to the creeping of superfluid Helium is named in his honor.

The Kamerlingh Onnes crater on the Moon was named after him by the IAU.
