Auguste Edouart is interesting to look at because not only is he a "true silhouette artist" like Lauren Muney and Karl Johnson but he came from the time when this almost extinct art form was hugely popular.  He was one of the many portrait artists from the time who travelled around from town to town and from country to country in search for clients.  Edouart lived from 1789 to 1861 and became very popular within that period.  He's done some landscape pictures aswell using watercolours, however he's mostly known for his silhouette portraits. Particularly his profiles of eminent Americans.  Here is some of his work.

Auguste Edouart is mostly known in France, England and the USA.  He's dead over 150 years but his work is still appreciated.
