Leon Hermant (1866–1936) was a French-American sculptor best known for his architectural sculpture. Hermant was born in France, educated in Europe and came to America in 1904 to work on the French Pavilion at the Louisiana Purchase Exposition in St. Louis, Missouri. For most of his career he was based in Chicago, working mostly in the American midwest, and frequently with a partner Carl Beil. In 1928 Hermant was awarded the Légion d'honneur by the French government for his Louis Pasteur Monument in Grant Park, Chicago.
