Cha-U-Kao

Cha-U-Kao was a French entertainer who performed at the Moulin Rouge and the Nouveau Cirque in the 1890s. Her stage name was also the name of a boisterous popular dance, similar to the can-can, which came from the French words "chahut", meaning "noise" and "chaos". She was depicted in a series of paintings by Henri de Toulouse-Lautrec. Cha-U-Kao soon became one of his favorite models.
