Pierre-Joseph Redouté

Pierre-Joseph Redouté was a painter and botanist from the Austrian Netherlands. He is best known for his watercolours of roses, lilies and other flowers, painted at the Château de Malmaison. Many were published as large coloured stipple engravings. Admirers nicknamed him "the Raphael of flowers", and he has often been ranked among the finest botanical illustrators.
