(b Saint-Hubert, Luxembourg [now in Luxembourg province, Belgium], 10 July 1759; d Paris, 20 June 1840).
French botanical illustrator of Flemish birth, the best-known member of a family of artists. He settled in Paris in 1782 and throughout his career he successfully negotiated France's varied political upheavals, becoming official flower painter in turn to Queen Marie Antoinette, both Napoleon's empresses (Josephine and Marie Louise), and Queen Marie Amélie (wife of King Louis Philippe). His large output included black-and-white illustrations for serious scientific treatises, but he is best known for lavish colour plates in deluxe books, notably Les Roses (1817–24). He was highly extravagant and died in debt in spite of his successful career.
