Monsieur Pierre was the professional name of Pierre Jean Philippe Zurcher-Margolle (born c. 1890, Toulon, France – died 1963, London). He was a professional dancer and dance teacher, largely responsible for introducing the Latin American dances to England, and for codifying them, and laying the groundwork for their use in competitions and in social dance. The system he and his colleagues developed became the basis for all Latin and American competitions held under the World Dance Council (WDC).
