Lamarck developed a particular interest for botany, and later, after he published a three-volume work "Flora française", he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the "Jardin des Plantes" and was appointed to the Chair of Botany in 1788. When the "Muséum national d'Histoire naturelle" was founded in 1793, Lamarck was appointed as a professor of zoology. In 1801, he published "Système des animaux sans vertèbres", a major work on the classifications of invertebrates. In an 1802 publication, he became one of the first to use the term "biology" in its modern sense. Lamarck continued his work as a top authority on invertebrate zoology.
