From Wikipedia, the free encyclopedia

Jean Claude Barthélemy Dufay (July 18, 1896–November 6, 1967) was a French astronomer.

During his career he studied nebulae, interstellar matter, the night sky and cometary physics. In 1925, while working in collaboration with Jean Cabannes, he computed the altitude of the Earth's ozone layer. He was named the honorary director of the Lyon and Haute-Provence observatories.[1][2]

He became a member of the French Academy of Sciences in 1963.[3] Dufay crater on the Moon was named after him.
