He was a French printmaker, caricaturist, painter, and sculptor, whose many works offer commentary on social and political life in France in the 19th century.

A prolific draftsman who produced over 4000 lithographs, he was perhaps best known for his caricatures of political figures and satires on the behavior of his countrymen, although posthumously the value of his painting has also been recognized.Daumier was born in Marseille to Jean-Baptiste Louis Daumier and Cécile Catherine Philippe. His father Jean-Baptiste was a glazier whose literary aspirations led him to move to Paris in 1814, seeking to be published as a poet.[2] In 1816 the young Daumier and his mother followed Jean-Baptiste to Paris. Daumier showed in his youth an irresistible inclination towards the artistic profession, which his father vainly tried to check by placing him first with a huissier, for whom he was employed as an errand boy, and later, with a bookseller. In 1822 he became protégé to Alexandre Lenoir, a friend of Daumier's father who was an artist and archaeologist. The following year Daumier entered the Académie Suisse. He also worked for a lithographer and publisher named Belliard, and made his first attempts at lithography.

Having mastered the techniques of lithography, Daumier began his artistic career by producing plates for music publishers, and illustrations for advertisements. This was followed by anonymous work for publishers, in which he emulated the style of Charlet and displayed considerable enthusiasm for the Napoleonic legend. Daumier was almost blind by 1873. During the reign of Louis Philippe, Charles Philipon launched the comic journal, La Caricature, Daumier joined its staff, which included such powerful artists as Devéria, Raffet and Grandville, and started upon his pictorial campaign of satire, targeting the foibles of the bourgeoisie, the corruption of the law and the incompetence of a blundering government. His caricature of the king as Gargantua led to Daumier's imprisonment for six months at Ste Pelagic in 1832. Soon after, the publication of La Caricature was discontinued, but Philipon provided a new field for Daumier's activity when he founded the Le Charivari.

Daumier produced his social caricatures for Le Charivari, in which he held bourgeois society up to ridicule in the figure of Robert Macaire, hero of a popular melodrama. In another series, L'histoire ancienne, he took aim at the constraining pseudo-classicism of the art of the period. In 1848 Daumier embarked again on his political campaign, still in the service of Le Charivari, which he left in 1860 and rejoined in 1864. Daumier was not only a prolific lithographer, draftsman and painter, but he also produced a notable number of sculptures in unbaked clay. In order to save these rare specimen from destruction, some of these busts were reproduced first in plaster. Bronze sculptures were posthumously produced from the plaster. The major 20th century foundries were Rudier and Valsuani.In addition to his prodigious activity in the field of caricature 3ƒ4 the list of Daumier's lithographed plates compiled in 1904 numbers no fewer than 3,958 3ƒ4 he also painted. Except for the searching truthfulness of his vision and the powerful directness of his brushwork, it would be difficult to recognize the creator of Robert Macaire, of Les Bas bleus, Les Bohémiens de Paris, and the Masques, in the paintings of Christ and His Apostles (Rijksmuseum in Amsterdam), or in his Good Samaritan, Don Quixote and Sancho Panza, Christ Mocked, or even in the sketches in the Ionides Collection at South Kensington. There is a splendid room-full of caricatures in the gallery "Am Romerholz" at Wintertur.

As a painter, Daumier, one of the pioneers of naturalism, did not meet with success until a year before his death in 1878, when M. Durand-Ruel collected his works for exhibition at his galleries and demonstrated the range of the talent of the man who has been called the "Michelangelo of caricature". At the time of the exhibition, Daumier was blind and living in a cottage at Valmondois, which Corot placed at his disposal. It was there that he died.
