Pierre Léna

Pierre Léna, born 1937, is a French astrophysicist. He is Emeritus Professor at the Université Paris-Diderot, associated with Paris Observatory. His scientific work focused on infrared astronomy and star formation. His interest in image quality led him to original world in image quality for astronomy, hence contributing to develop adaptive optics and the interferometric mode of the European Very Large Telescope (VLT) in Chile, both making today the VLT a unique instrument in the world, for example leading to a wealth of new results on stars, exoplanets and black holes.
With Georges Charpak (Nobel laureate in physics 1992) and Yves Quéré, with the full support of the French Académie des sciences, he co-founded in 1996 the movement La main à la pâte. The goal was, and remains, to contribute to a renovation of early science education in primary and middle schools: focusing on active students, experimenting and observing, developing their language abilities to concretely practice science, and helping teachers to implement this inquiry-based science education (IBSE). Born in France, this action quickly expanded in the early 2000s, with collaborations all over the world, involving high repute scientists, science Academies and ministries of education. Pierre Léna chaired in 2007-2011 the InterAcademy Partnership Science education program. In 2011 the French Académie des sciences created the Foundation La main à la pâte, which he chaired and of which he currently is Honorary President. In 2018, in order to support the education aspects of the Paris Agreement and the IPCC actions, he developed the Office for Climate Education in connection with the InterAcademy Partnership, and prepared the designation of OCE as a Unesco Category 2 Center, achieved end 2019.
Pierre Léna belongs to the French Académie des sciences, the Pontifical Academy of Sciences and several other Academies.
