André Michaux, also styled Andrew Michaud, was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include Histoire des chênes de l'Amérique and Flora Boreali-Americana which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist.
