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.

Dance is an art form, often classified as a sport, consisting of sequences of body movements with aesthetic and often symbolic value, either improvised or purposefully selected. Dance can be categorized and described by its choreography, by its repertoire of movements or by its historical period or place of origin. Dance is typically performed with musical accompaniment, and sometimes with the dancer simultaneously using a musical instrument themselves.
