Jean-Baptiste Debret (18 April 1768 – 28 June 1848) was a French painter, who produced many valuable lithographs depicting the people of Brazil.
Debret studied at the French Academy of Fine Arts, a pupil of the great Jacques-Louis David (1748–1825) to whom he was related. He accompanied David to Rome in the 1780s. His debut was at the Salon des Beaux Arts of 1798, where he got the second prize.
He travelled to Brazil in March 1816 as a member of the so-called French Artistic Mission, a group of bonapartist French artists and artisans bound to creating in Rio de Janeiro an arts and crafts lyceum (Escola Real de Artes e Ofícios) under the auspices of King D. João VI and the Conde da Barca, which later became the Academia Imperial de Belas Artes (Imperial Academy of Fine Arts) under Emperor Dom Pedro I.
As a painter favored first by the Portuguese court in exile and later by the imperial court in Rio, Debret was often commissioned to paint portraits of many of its members, such as Portuguese king Dom João VI and the Archduchess Maria Leopoldina of Austria, the first empress of Brazil, who married D. Pedro I (Debret was commissioned to produce a painting of her arrival for the marriage at the Rio port, as well as the public acclaiming of the new Emperor). He established his at the Imperial Academy in December 1822 and became a valued teacher in 1826. In 1829 Debret organized the first arts exhibition ever to take place in Brazil, in which he presented many of his works as well as of his disciples. Emulating David's role during the French Empire, Debret was also involved in the drawing ornaments for many of public ceremonies and official festivities of the court and even some of the courtier's uniforms are credited to him.
