Heike Kamerlingh Onnes a "Kamerlingh Onnes Laboratorium" named after him, as well as a plaque and several machines used by Kamerling Onnes in the main hall of the physics department. The Kamerlingh Onnes Award was established in his honour, recognising further advances in low-temperature science. The Onnes effect referring to the creeping of superfluid helium is named in his honor. The crater Kamerlingh Onnes on the Moon is named after him. Onnes is also credited with coining the word "enthalpy". Onnes' discovery of superconductivity was named an IEEE Milestone in 2011.

Lowest temperature recorded on Earth 1960, held the record until a temperature of was measured at the Soviet Vostok Station, on the Antarctic Plateau, on July 21, 1983. This remains the record for a directly recorded temperature. In 1904 Dutch scientist Heike Kamerlingh Onnes created a special lab in Leiden with the aim of producing liquid helium. In 1908 he managed to lower the temperature to less than −269 °C (-452.2 F, 4 K), which is less than four degrees above absolute zero. Only in this exceptionally cold state will helium liquefy, the boiling point of helium being at −268.94 °C (-452.092 F). Kamerlingh Onnes
