"Joseph-Siffred Duplessis (22 September 1725 – 1 April 1802) was a French painter known for the clarity and immediacy of his portraits.
He was born in Carpentras, ...
near Avignon, into a family with an artistic bent and received his first training from his father, a surgeon and talented amateur. He subsequently studied with Joseph Gabriel Imbert (1666–1749), who had been a pupil of Charles Le Brun. From 1744–47 or later he worked in Rome, in the atelier of Pierre Subleyras (1699–1749), who was also from the south of France. In Italy Duplessis became fast friends with Joseph Vernet, another Occitan." - (en.wikipedia.org 23.05.2021)
