Jean Baptiste Madou (Feb 3, 1796 – Mar 31, 1877), was a Belgian painter and lithographer.
Madou was born in Brussels. He studied at the Brussels Academy of Fine Arts and was a pupil of Pierre Joseph Célestin François. While draftsman to the topographical military division at Kortrijk, he received a commission for lithographic work from a Brussels publisher. It was about 1820 that he began his artistic career.
Between 1825 and 1827 he contributed to Les Vues pittoresques de la Belgique, to a Life of Napoleon, and to works on the costumes of the Netherlands, and later made a great reputation by his work in La Physionomie de la société en Europe depuis 1400 jusqu’à nos jours and Les Scenes de la vie des peintres.
It was not until about 1840 that Madou began to paint in oils, and the success of his early efforts in this medium resulted in a long series of pictures representing scenes of village and city life, including The Fiddler, The Jewel Merchant, The Police Court, The Drunkard, The Ill-regulated Household, and The Village Politicians.
