(b Ghent, 23 July 1823; d Ghent, 16 July 1904). Belgian painter and etcher. He initially studied music at the Ghent Conservatory. Then, under the influence of his elder brother, the landscape painter Xavier De Cock (1818–96), he took courses in painting at the Art Academy in Ghent with Félix De Vigne (1806–62). In 1855 he went to Paris where he worked as a musician, but deafness forced him to devote himself instead to painting. He became friends with Jean-Baptiste-Camille Corot and, like his brother, stayed in Barbizon with Narcisse Diaz, Charles-François Daubigny, Théodore Rousseau and Constant Troyon. He also visited Gasny, Normandy, where he painted Evening in Normandy, Surroundings of Saint-Christophe and Surroundings of Gasny (all Ghent, Mus. S. Kst.). From 1857 he exhibited regularly at the Paris Salon and won medals there in 1867 and 1869. After several brief stays in Paris, he settled definitively in Ghent in 1880.
