Rudolf (von) Laban, also known as Rudolph von Laban, was an Austro-Hungarian, German and British dance artist, choreographer and dance theorist. He is considered a "founding father of expressionist dance", and a pioneer of modern dance. His theoretical innovations included Laban movement analysis and Labanotation, which paved the way for further developments in dance notation and movement analysis. He initiated one of the main approaches to dance therapy. His work on theatrical movement has also been influential. He attempted to apply his ideas to several other fields, including architecture, education, industry, and management.
