Pierre Jacquinot

Pierre Jacquinot (* January 18, 1910, † 22 September 2002) was a French physicist who dealt with spectroscopy and atomic physics.

Jacquinot studied at the University of Nancy, where he was in 1930 erwarb.1932 his degree in physics, he first in the national competition for the aggregation in physics. He was in Paris ( in the High Magnetic Field Laboratory in Bellevue) doctorate at Aimé Cotton with a thesis on the Zeeman effect in strong magnetic fields while at the same time, he conducted research in the predecessor organization of the CNRS in. During the Second World War, he was from 1942 professor of physics at the University of Clermont -Ferrand. From 1946 he was again in Paris, where he became a lecturer ( Maitre de conferences ) and from 1950 professor, from 1954 to the Chair of spectroscopy. In 1951 he became head of the named after his death by Aimé Cotton laboratory. Later he was director of SupOptique ( Institut d' optique théorique et appliquée ) to succeed Kastler and professor at the University of Paris XI. In 1978 he retired. In his professorship and in the direction of the Laboratory Aimé Cotton

Jacquinot developed with his student Pierre Connes and others in the 1950s, methods of Fourier spectroscopy (Fourier Transform Spectrometer). Later he worked on laser spectroscopy.

1962 to 1969 he was Director General of the CNRS. Under his leadership, the connection was reinforced to the universities and founded first the CNRS associated laboratories. In 1978 he was awarded the Médaille d' or du CNRS. He was a member of the Academie des Sciences, and its president from 1980 to 1982. He was also temporarily President of the French Physical Society.
