Charles Peyrou (born May 18, 1918 in Oloron-Sainte-Marie , † April 6, 2003 ) was a French experimental particle physicist at CERN .

Peyrou studied at the École polytechnique , where he was a student of Louis Leprince-Ringuet and made experiments to observe cosmic radiation. In 1938 he and his group built a Wilson chamber for this purpose . After the Second World War he resumed observations with cloud chambers on the Pic du Midi de Bigorre . The laboratory there studied strange particles such as the first observation of the decay of the K meson into muons and neutrinos . From 1946 to 1954 he was a lecturer at the École Polytechnique and from 1954 to 1958 professor at the University of Bern , where he lectured until 1974. At the same time he was involved in the development of CERN from 1957. There he headed the bubble chamber group and from 1961 the track chamber department (further developments of the bubble chamber). In 1966 he became director of the Physics II department at CERN, which he remained until 1976. He was involved in the development of various bubble chamber detectors at CERN up to the BEBC, which was equipped with superconducting magnets.

In 1973 he received the Prix ​​Félix Robin .
