Edouard Mielche (Copenhagen, 1905–1969) was an influential Danish set designer and theatre director, a central figure in the renewal of the 20th-century Nordic stage. Associated for much of his career with the Royal Danish Theatre, where he debuted in 1927, he was distinguished by an innovative approach that broke with the naturalist tradition. His set designs, often expressionist or modernist in style, used light, colour, and bold architectural structures to create psychological and symbolic atmospheres, rather than realistically reproducing settings. His most celebrated works include the sets for the ballet *Qarrtsiluni* (1942), in collaboration with choreographer Harald Lander; the play *Idioten* (The Idiot); and the opera *Gudrun*. His significant artistic contribution was recognised with prestigious awards, including the Eckersberg Medal in 1940 and the Thorvaldsen Medal in 1965, Denmark's highest honour for the visual arts.
