Much of Jussieu’s classification of flowering plants is still in use. Bernard de Jussieu was an uncle and an important influence. Jussieu was godfather to one of Lamarck’s sons; Lamarck and Fourcroy were colleagues of Jussieu at the Jardin des Plantes, while Berthollet and Fourcroy were with Jussieu fellow-members of a project led by Lavoisier to better understand the role of vegetation in the natural cycle. Hooker and Owen were met on visits to England. De Candolle was an early supporter of Jussieu’s system, Banks and Ampère correspondents, and Bonpland a student then friend.
