In 1911, Heike Kamerlingh Onnes, Dutch physicist and Director at the University of Leiden’s Cryogenic Laboratory, discovered that if you cool mercury to just above 4 degrees Kelvin (-269 degrees C, a few degrees short of absolute zero), mercury would exhibit almost no electrical resistance.

Prof Heike Kamerlingh Onnes (Dutch: [ˈɔnÉ™s]) 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. - Superconductivity – Wikipedia
Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance of solid mercury at cryogenic temperatures using the recently produced liquid helium as a refrigerant. At the temperature of 4.2 K, he observed that the resistance abruptly disappeared. - Q & A: Magnetism of Mercury | Department of Physics | University …
At room temperature, the element mercury is not very magnetic at all. … In fact, superconductivity was discovered by Kamerlingh Onnes in 1911 by studying mercury at low temperatures. Superconductors generally expel magnetic fields, so you could say that below 4 K, mercury is a perfect diamagnet. - Mercury-containing oxides offer new perspective on mechanism of …
Apr 15, 2011 – In classical superconductors such as mercury, superconductivity arises through the combined vibrations of the atoms in the crystal. This makes … - List of superconductors – Wikipedia
