Félix Delamarche became the owner of his father's map publishing company, Maison Delamarche. He ran the company alongside cartographer Charles Dien. The firm would eventually be passed down to Alexandre Delamarche. Delamarche created "Atlas de la géographie ancienne et moderne" in 1820. The atlas was reprinted during the 19th century. It was utilized by the Ecole Spéciale Militaire de Saint-Cyr. His work is held in the collection of the Library of Congress.
