On 8 April in 1911 Heike Kamerlingh Onnes, dipped a wire made of solid mercury into liquid helium and lowered the temperature. At 4.2 K, the wire's electrical resistance suddenly vanished. Onnes wrote in his lab book: "Mercury has passed into a new state, which on account of its extraordinary electrical properties may be called the superconductive state." He had discovered superconductivity!
