Léon Joseph Florentin Bonnat (June 20, 1833 - September 8, 1922) was a French painter, Grand Officer of the Légion d'honneur, art collector and professor at the Ecole des Beaux Arts.
Bonnat's vivid portraits of contemporary celebrities are his most characteristic works, but his most important works are arguably his powerful religious paintings, such as his Christ on the Cross (now in the collection of the Musée du Petit Palais in Paris, but not currently on display), Job (in the Musée Bonnat), St Vincent Taking the Place of Two Galley Slaves (at the church of Saint-Nicholas des Champs in Paris), and the large Martyrdom of St Denis for the Pantheon in Paris. However, he received few commissions for religious and historical paintings, and most of his output consists of portraits. He also produced genre paintings of Italian peasants, and a small number of Orientalist scenes, the most famous of which is The Barber of Suez piece presented here.
As a teacher he encouraged freedom of expression and execution. He recommended traveling to Madrid to visit the Prado Museum, and introduced in Paris the tendency paint in the Spanish way, which influenced the evolution of French painting.
