Gustave Clarence Rodolphe Boulanger was a French figure painter and Academic artist and teacher known for his Classical and Orientalist subjects.

Boulanger was born in Paris in 1824. He never knew his father, and when his mother's death left him orphaned at the age of fourteen, he became the ward of his uncle, Constant Desbrosses, who in 1840 sent him to study first under the history painter Pierre-Jules Jollivet and then at the atelier of Paul Delaroche, where Boulanger met and befriended his fellow student Jean-Léon Gérôme.

Boulanger and Gérome would become leading lights of the Néo-Grec movement in French art, which revisited the fascination of previous generations for the Classical world, but brought to its austere subject matter subversive touches of whimsy, sensuality, and eroticism. "When they appear on the contemporary art scene, the Néo-Grecs will be defended as rejuvenators of the Classical tradition by some, condemned as gravediggers of history painting by others…they rarely give an orthodox image of Antiquity, some, like Gérôme, Boulanger and Hamon, not hesitating to choose licentious subjects, to parody mythological characters, or to invent very personal allegories of Antiquity."

In 1845, Boulanger was sent by his uncle to Algeria to tend to Desbrosses's business interests there. Boulanger was fascinated by all he saw, and what was planned as a two-month stay turned to eight, until Desbrosses threatened to cut off his funds. Boulanger brought back a large number of sketches which he used for his first Orientalist paintings. (This was the first of at least three trips to North Africa, including one in 1872 with Gérôme.)

In 1848 and 1849, he shared communal living and working quarters with other artists of the Néo-Grec movement at the Chalet, 27 rue de Fleurus. The group also gathered at the atelier of Gérôme on rue de Sevres. Boulanger turned his efforts to winning the Prix de Rome, and with it, a scholarship to the Académie de France à Rome. In 1848, he obtained second place with Saint Pierre chez Marie, and the next year he won the Grand Prix with Ulysse reconnu par Euryclée and departed for Rome, where he would remain until 1855. His education and research included study at the excavations of Pompeii. He also traveled to Greece.

Each year, the students at Rome sent back to the Academy in Paris a painting to demonstrate their progress, and for public exhibition; Boulanger's works repeatedly disappointed the Academy and scandalized critics, beginning with the first, Phryné, in 1850. Wrote one reviewer:

M. Boulanger, a first year pensionnaire, spent a lot of patience to paint with great finesse…a fat naked woman with red hair and slanted blue eyes, seated on rags of all colors and a scrap of cushion on which is engraved in Greek letters her name: Phryné. To take on this marvelous beauty who inspired Praxiteles' masterpiece and the famous Venus of Apelles, an artist must impose on himself the most severe purity of design, the utmost simplicity of line, the calm splendor of beauty. M. Boulanger's Phryné is far from responding to this program.
In 1856, when his studies at Rome were complete, Boulanger took a second trip to North Africa, and then returned to Paris. Boulanger moved into his own atelier at rue de La Rochefoucauld, 64, but continued to meet and socialize with the other Néo-Grecs. He became one of Jean-Léon Gérôme's closest friends; after 1863, Gérôme regularly entrusted him with the management of his studio at the École des Beaux-Arts during his travels in the East.

In 1855, Prince Napoléon, cousin of Napoleon III, decided to build a palace inspired by the villas of Pompeii, in particular by the Villa of Diomedes. The palace had rooms around an atrium open to the sky with a shallow pool below. Busts of the Bonaparte family surrounded the atrium, with a white marble statue of Napoleon I presiding in the guise of a deified Caesar. Gérôme took part in the project by making three paintings that he considered "perhaps the most beautiful things he ever signed."

The Pompeiian palace was inaugurated on 14 February, 1860, in the presence of the Emperor and Empress. Théophile Gautier was present to hear the recitation of his poem written for the occasion, La Femme de Diomède: Prologue. Then famous actors of the Théâtre-Français and the Comedie-Française performed The Flute Player, a play by Emile Augier, a friend of Gautier and the Néo-Grecs.

Boulanger's Répétition théâtrale dans la maison d’un poète romain at the Salon of 1855 played a part in inspiring both the Pompeiian palace and its inauguration with a play. Boulanger was privileged to immortalize the occasion with a work presented at the Salon of 1861, Répétition du "Joueur de flûte" et de la "Femme de Diomède" chez le prince Napoléon (Rehearsal of "The Flute Player" and "Wife of Diomedes" at the Place of Prince Napoléon). The painting depicts not the performance itself but a rehearsal, with only writers, actors, and a Black slave present.

When the enemy forces approached Paris in 1870, like many of the artists who stayed in Paris, having neither enlisted in the army nor fled abroad, Boulanger became a member of the National Guard, joining ranks with his friend Charles Garnier, as well as Edgar Degas, Edouard Manet, Auguste Rodin, and Louis Émile Benassit.

As normal life and all previous projects came to a stop, Boulanger painted a series of works documenting the momentous events. These scenes of fire and carnage, quite unlike anything else in his oeuvre, are in the collection of the Musée Carnavalet.
