Maurice Jules Gaston Corneille Caullery (5 September 1868, Bergues – 13 July 1958, Paris) was a French biologist.

Biography He was born in Bergues in north France on 5 September 1868. His early education was in Douai.

He began as a lecturer in zoology at Lyon in 1897. From 1901 to 1903 he was a lecturer at the faculty of sciences in Marseille, and from 1903 to 1909, taught classes at the Sorbonne (laboratory of ). In 1909 he succeeded Alfred Mathieu Giard (1846-1908) as director of the zoological station in Wimereux. In 1923 he opened a new laboratory of on Boulevard Raspail in Paris.

Caullery specialised in parasitic protozoans and marine invertebrates. He also worked on insects. His research of Siboglinum weberi was to become the foundation for establishing the family of beard worms known today as Siboglinidae. Also, he investigated how the various biological aspects of tunicates and annelids impacted their evolution.

In 1915 he was elected president of the Société zoologique de France, and later on in his career, he served as president of the Académie des Sciences (1945) and the Société de biologie (1946).

Evolution

Caullery was an advocate of Lamarckian evolution and Mendelism. He argued that modern evolution had stopped and the Lamarckian mechanism had "run out of steam", leaving Mendelian processes in operation.
