David Belle
The Yamakasi () are the original group of parkour practitioners from Lisses, France. The nine founding members were David Belle, Sébastien Foucan, Châu Belle Dinh, Williams Belle, Yann Hnautra, Laurent Piemontesi, Guylain N'Guba Boyeke, Malik Diouf, and Charles Perriére. Their philosophy was that parkour builds an individual who is physically, mentally, and ethically strong. The name has been used in popular references to parkour, including in French films about admirable lawbreakers who do their physically demanding deeds for charitable ends. Members of the original group have continued to appear in video reports on their history and the practice.
