What is Heike Kamerlingh Onnes most famous for?
My primary renown stems from the successful liquefaction of helium and, consequently, the exploration of matter at extraordinarily low temperatures. It was within this cryogenic domain that we observed a phenomenon of profound significance: superconductivity. In 1911, experiments conducted on pure mercury revealed that its electrical resistance vanished entirely below a critical temperature. This discovery, detailed in my work 'The Resistance of Pure Mercury at Helium Temperatures,' opened a new chapter in physics, demonstrating that at the brink of absolute zero, the very nature of electrical conduction could be fundamentally altered. The Leiden Cryogenics Laboratory, which I established, became the crucible for these investigations, pushing the boundaries of what was then achievable.
