Roerich, Nicholas Konstantin, 1874-1947, Russian artist, scene designer, and archaeologist. He was connected with the Moscow Art Theatre and the Diaghilev ballet. His stage sets for Stravinsky's Sacre du printemps (1913) revealed him as a brilliant colorist. He traveled to the United States where the Roerich Museum, New York City, was founded (1923) in his honor. His exploration of the Himalayas resulted in 500 pictures. He is represented in the chief European collections and many American galleries. Among his books are Heart of Asia (1929) and Realm of Light (1931).
