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.
Published worksDuring 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 Pelagie 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.
Around the mid 1840's Daumier started publishing his famous caricatures depicting members of the legal profession, known as 'Les Gens de Justice', a scathing satire about judges, defendants, attorneys and corrupt, greedy lawyers in general. A number of extremely rare albums appeared on white paper, covering 39 different legal themes, of which 37 had previously been published in the Charivari. It is said that Daumier's own experience as an employee in a bailiff's office during his youth may have influenced his rather negative attitude towards the legal profession.
