Ernest Cosson

Ernest Saint-Charles Cosson (22 July 1819 – 31 December 1889) was a French botanist born in Paris.

Cosson is known for his botanical research in North Africa, and during his career he participated in eight trips to Algeria.

In several of these he was accompanied by Henri-René Le Tourneux de la Perraudière (1831–1861),[1] whom he honoured in the naming of several species and genera (e.g., Perralderia, Galium perralderii).

In 1863 he was elected president of the Société botanique de France, and from 1873 to 1889, he was a member of the Académie des sciences.

[2] In 1882 Jules Ferry, as Minister of Public Instruction, decided to create a mission to explore the Regency of Tunisia.
