Pierre Weiss


French physicist, specializing in magnetism, who developed the domain theory of ferromagnetism in 1907. Weiss domains and the Weiss magneton are named after him. Weiss also developed the molecular or mean field theory, which is often called Weiss-mean-field theory, that led to the discovery of the Curie-Weiss law. Alongside Auguste Picard, Pierre Weiss is considered one of the first discoverers of the magnetocaloric effect in 1917.

Pierre Weiss made several experimental discoveries that led to the development of the strongest electromagnets of the beginning of the 20th century. He worked at the universities of Rennes, Lyon, ETH Zurich where he was raised, and finally at Strasbourg. In these academic institutions he founded several renowned laboratories.

He died on 24 October 1940, aged 75, in Lyon.
