Daniel Barbier (10 December 1907 – 1 April 1965) was a French astronomer born in Lyon.[1]

Between 1930 and 1965 he published nearly 100 scientific papers on astronomy. Among his works were studies of stellar atmospheres and lunar occultations and eclipses. He performed studies of the upper atmosphere, Aurora Borealis, the zodiacal light and the night airglow.

His name remains associated to the famous Eddington-Barbier relationships of analytical radiative transfer (see Barbier 1943[2] and Paletou 2018[3]).

The crater Barbier on the Moon is named after him.
