He was active from 1699 to 1730, and is mainly known for his Rococo Chinoiserie or Orientalist paintings,[1] and decorative objects and scenes.
[2] He painted scenery for the Paris Opera (then the Académie Royale de Musique) around the turn of the eighteenth century.
He was appointed “peintre et dessinateur de la Manufacture” in 1721, a position responsible for training artists, creating six designs annually, and restoring tapestries and cartoons.
He held the post until 1726, when the new director Noël-Antoine de Mérou replaced him with Jean-Baptiste Oudry as chief painter.
The last known work signed by Duplessis was a tripartite screen dated 1730, once in the possession of art dealer Jacques Helft.
