Egide Charles Gustave, Baron Wappers (23 August 1803 - 6 December 1874) was a Belgian painter. His work is generally considered to be Flemish and he signed his work with the Flemish form of his name, Gustaf Wappers.
He studied at the Royal Academy of Fine Arts in Antwerp, and during 1826 in Paris. The Romantic movement with its new ideas about art and politics was astir in France. Wappers was the first Belgian artist to take advantage of this state of affairs, and his first painting, "The Devotion of the Burgomaster of Leiden," appeared at the appropriate moment and had great success in the Brussels Salon in 1830, the year of the Belgian Revolution. While political, this remarkable work revolutionized the direction of Flemish painters.
