Heike Kamerlingh Onnes

Heike Kamerlingh Onnes was a Dutch physicist and Nobel laureate. He exploited the HampsonLinde cycle to investigate how materials behave when cooled to nearly absolute zero and later to liquefy helium for the first time. His production of extreme cryogenic temperatures led to his discovery of superconductivity in 1911 for certain materials, electrical resistance abruptly vanishes at very low temperatures.

Kamerlingh Onnes was born in Groningen, Netherlands. His father, Harm Kamerlingh Onnes, was a brickworks owner. His mother was Anna Gerdina Coers of Arnhem.
