François Roddier
François Roddier (1936 – 19 August 2023) was a French physicist and astronomer.

Biography 
François Roddier was born in 1936 in Paris. He received his baccalauréat degree in Lyon in 1954. In 1956 he received a degree from the École normale supérieure (Paris) in Physical Sciences. In 1960, he entered French National Centre for Scientific Research in the Sciences of the Universe section where he completed his doctoral thesis under the direction of Jacques Blamont. There he developed an atomic jet spectrograph and used it to study the Sun. He defended his thesis in 1964. In 1965, he was named professor at the Université de Nice where he created a department of astrophysics. He formed a research group in helioseismology. He was interested in the optical effects of atmospheric turbulence and developed high angular resolution interferometric observation methods with his spouse Claude Roddier.

In 1984, he immigrated with his family to the United States to work for the National Optical Astronomy Observatory where he participated in the development of adaptive optics. He proposed a new type of wavefront sensor called a curvature sensor. In 1988 he moved to the Institute for Astrophysics at the University of Hawaii where he created a group for the research and development of adaptive optics. This group built the first adaptive optics system based on bimorph deformable mirrors and curvature sensors. The principle would be used in the adaptive optics systems in the Canada–France–Hawaii Telescope, for that of the Japanese Subaru Telescope, and for the MACAO system of the European Southern Observatory.

Roddier retired in December 2000 and returned to live in France. During his retirement, he became interested in thermodynamic aspects of evolution. 

François Roddier died on 19 August 2023, at the age of 86.
