Thomas Say [SEP] Career
He became an apothecary. A self-taught naturalist, Say helped found the Academy of Natural Sciences of Philadelphia (ANSP) in 1812. In 1816, he met Charles Alexandre Lesueur, a French naturalist, malacologist, and ichthyologist who soon became a member of the Academy and served as its curator until 1824. At the Academy, Say began his work on what he would publish as "American Entomology". To collect insects, he made numerous expeditions to frontier areas, risking American Indian attacks and hazards of traveling in wild countryside. In 1818, Say accompanied his friend William Maclure, then the ANSP president and father of American geology; Gerhard Troost, a geologist; and other members of the Academy on a geological expedition to the off-shore islands of Georgia and Florida, then a Spanish colony.
