Eustache Le Sueur (baptized Nov. 19, 1617, Paris, France—died April 30, 1655, Paris) was a painter known for his religious pictures in the style of the French classical Baroque. Le Sueur was one of the founders and first professors of the Royal Academy of Painting and Sculpture.
Le Sueur studied under the painter Simon Vouet and was admitted at an early age into the guild of master painters. Some paintings reproduced in tapestry brought him notice, and his reputation was further enhanced by a series of decorations for the Hôtel Lambert that he left uncompleted. He painted many pictures for churches and convents, among the most important being The Sermon of Saint Paul at Ephesus, and his famous series of 22 paintings of the Life of St. Bruno, executed in the cloister of the Chartreux. Stylistically dominated by the art of Nicolas Poussin, Raphael, and Vouet, Le Sueur had a graceful facility in drawing and was always restrained in composition by a fastidious taste.
