... was first postulated in 1930 by the Austrian physicist Wolfgang Pauli, to explain how beta decay could conserve energy, momentum, and angular momentum (spin). It was detected in 1956 by the American physicists Clyde Cowan and Frederick Reines; their work was rewarded with the Nobel Prize in 1995.
(In 1930, Pauli was working in Zurich; he moved to the United States in 1940, having been denied Swiss citizenship, and was naturalised in 1946. He then returned to Switzerland, and became a Swiss citizen in 1949.)
An experiment at CERN in 2011 apppeared to show that neutrinos travelled faster than light, but this was shown in 2012 to be untrue.
