Jean-Étienne Liotard (French pronunciation: ?[?an?etj?n lj?ta?]; 22 December 1702 – 12 June 1789) was a Swiss painter, art connoisseur and dealer.
He is best known for his portraits in pastel, and for the works from his trip to Turkey.
A Huguenot of French origin and citizen of the Republic of Geneva, he was born and died in Geneva, but spent most of his career in stays in the capitals of Europe, where his portraits were much in demand.
He worked in Rome, Istanbul, Paris, Vienna, London and other cities.
