Biography

Born in Lyon, he was the son of engineer Eugene Locard. He was a student at École Centrale Paris. He is considered one of the more prolific malacologists of the so-called "new school" with Jules René Bourguignat (1828–1892) as his master.

Locard is credited with describing hundreds of zoological species, in particular freshwater mussels and gastropods from the genus ''Helix''. During his career he did very little collecting of specimens himself, preferring to work in an institution/museum environment. In 1895, he revised the conchological collection of Jacques Philippe Raymond Draparnaud (1772–1804).

Among his many publications are articles on the geology of the Lyon region, and treatises on fossil and living mollusks. He was the author of detailed biographies of naturalists, such as Martial Étienne Mulsant (1797–1880) and Gaspard Michaud (1795–1880), and also wrote an article on Lyonnaise malacologists, titled ''Malacologistes lyonnais'' (1879). In 1877 he published ''Malacologie Lyonnaise; ou Description des mollusques terrestres & aquatiques des environs de Lyons'' (1877), based on Ange Paulin Terver's collection of terrestrial and aquatic mollusks found in the vicinity of Lyon.
In 1893 Philippe Thomas published the palaeontology results of the Tunisian Scientific Exploration Mission (1885–86) in six instalments plus an atlas, giving the work of Victor-Auguste Gauthier (sea urchins), Arnould Locard (Mollusca), Auguste Péron (Brachiopods, Bryozoa and Pentacrinitess) and Henri Émile Sauvage (fish).

Locard was a member of the ''Académie des sciences, belles-lettres et arts de Lyon'' (1879–1904), the ''Société française de malacologie'', the ''Société géologique de France'' and the ''Société linnéenne de Lyon'' 1881–1904, president- 1882). He was a founding member of the ''Association lyonnaise des amis des sciences naturelles''.
