Louis Marie Adolphe Olivier Édouard Joubin (27 February 1861 in Épinal – 24 April 1935 in Paris)[1] was a professor at the Muséum national d'Histoire naturelle in Paris. He published works on nemerteans, chaetognatha, cephalopods, and other molluscs.[2]
He served as an assistant to Henri de Lacaze-Duthiers, subsequently becoming director of the laboratories at Banyuls-sur-Mer (1882) and Roscoff (1884). Later on, he became an instructor at the University of Rennes,[3] and in 1903 succeeded Edmond Perrier as chaire des mollusques, des vers et des zoophytes at the Muséum national d'Histoire naturelle (from 1917 onward his title was chaire des mollusques).[4] In 1906 he was chosen by Albert I, Prince of Monaco to be in charge of instruction at the Institut océanographique.[3]
In 1905 he was named president of the Société zoologique de France. In 1920 he became a member of the Académie des Sciences.[3]
Joubin's squid (Joubiniteuthis portieri) is named for him,[5] as is Anoxycalyx joubini, a hexactinellid sponge whose lifespan is purportedly 10,000 years.[6]
