Heike Kamerlingh Onnes when his notebook was deciphered a century later). He reported that ""Mercury has passed into a new state, which on account of its extraordinary electrical properties may be called the superconductive state"". He published more articles about the phenomenon, initially referring to it as ""supraconductivity"" and, only later adopting the term "superconductivity". Kamerlingh Onnes received widespread recognition for his work, including the 1913 Nobel Prize in Physics for (in the words of the committee) ""his investigations on the properties of matter at low temperatures which led, "inter alia", to the production of liquid helium"". Some of the instruments he devised
Pieter Rijke 1836. The title of his Ph.D. thesis was "De origine electricitatis voltaicae". In 1835 he was appointed professor of physics at the Royal Athenaeum in Maastricht. In 1845 he became extraordinary professor and in 1854 he was promoted to full professor of physics at the University of Leiden. There he started a physics laboratory with a large collection of scientific instruments. His most important students were H.A. Lorentz and J.D. van der Waals. He retired in 1882, and was succeeded by Heike Kamerlingh Onnes as professor of experimental physics at the University of Leiden. Rijke became a member of the
