Robert J. Lang has been an origami student for over forty years and is now recognized as one of the world’s leading masters of the art. Lang has over 500 designs catalogued and diagrammed. He is known for designs of great detail and realism, and some of his creations were recognized as “the most complex origami designs ever created’. Lang’s work combines aspects of “the Western school of mathematical origami design with the Eastern emphasis upon line and form to yield models that are at once distinctive, elegant, and challenging to fold”. They have been shown in exhibitions in New York (Museum of Modern Art), Paris (Carrousel du Louvre), Salem (Peabody Essex Museum), San Diego (Mingei Museum of World Folk Art), and Kaga, Japan (Nippon Museum Of Origami), among others.
