Pierre Léna
Pierre Léna (born November 22, 1937 in Paris ) is a French astrophysicist and astronomer.
Pierre Léna studied physics at the École normal supérieure from 1956 to 1960 , acquired the Agrégation in physics and received his doctorate in 1969. As a post-doctoral student , he was at the Kitt Peak National Observatory . Then he was at the University of Paris in Orsay and from 1973 professor at the University of Paris VII (Denis Diderot). He also conducted research at the Paris Observatory in Meudon (LESIA). From 1971 to 1983 he headed the laboratory for infrared astronomy of the CNRS . In 2004 he retired.
He operated infrared astronomy from Earth, from airplanes and satellites (camera of the Infrared Space Observatory ). From the end of the 1970s he dealt with interferometric techniques and adaptive optics (with tests at the Observatoire de Haute-Provence in 1989), so he was involved in the design of the Very Large Telescope . In 1979 he was one of the first to take high-resolution images of star formation.
He also proposed the use of adaptive optics for examining the retina in ophthalmic medicine (1998) and participated in its development.
In 1973 he set up the instruments for observing a total solar eclipse in Africa with the Concorde.
He wrote popular science books and is involved in the La Main à la pâte program for teaching natural sciences in schools from elementary schools, initiated by Georges Charpak . Yves Quéré was also involved . From 2011 to 2014 he was president of the foundation of the same name and then its honorary president.
From 2003 to 2007 he was a member of the CNRS Ethics Committee. Since 1991 he has been a member of the Académie des Sciences . In 1989 he was president of the Société française de physique. He is a member of the Academia Europaea (2005) and the Academies of Sciences of Liege, Argentina, Chile and Venezuela and the Pontifical Academy of Sciences.
In 1979 he was awarded the Benjamin Valz Prize, in 1986 the Henri de Parville Prize, in 1995 the Prix Holweck , in 1996 the Prix Maurice-Pérouse of the Fondation de France and in 1999 the Prix Jules Janssen. In 2006 he received the Erasmus Medal. He is an officer of the Legion of Honor and commander of the Ordre national du mérite .
He has four children.
