The silhouette was named after Etienne de Silhouette, who was a tight-fisted banker who produced a cheap form of art.
Etienne de Silhouette was a financier, in France during the 18th century.
He raised a great deal of money for the Crown but was very mean about spending it, especially on Court salaries. When he was removed from his job as Controller-General, he made a living for himself by producing portraits of famous people. He used the simple and cheap method of drawing outlines of them, tracing their shadows thrown by a light on to a screen.
These 'silhouettes' became extremely fashionable. Another fashion that bore his name was a type of coat that had no pockets.
Who needed pockets when he was too mean to put any money into them, anyway?
