Albert Dubosq Albert Émile Clément Dubosq (often misspelled 'Duboscq'; 1863–1940) is one of the most prolific Belgian scenographers of the Belle Époque. Between 1890 and 1925 Dubosq decorated 446 theatrical entertainments of virtually every possible kind: ballet, circus, (melo)drama, opera, operetta, pantomime, revue, and vaudeville. Dubosq is furthermore one of the few scenic painters of his generation to have left a substantial sample of his art, namely twenty-one (near-)complete sets. Comprising Europe’s largest holding of historical decors, the hundreds of flats and drops of the ‘Dubosq’ collection have survived at the Schouwburg of Kortrijk since 1920.
