Gilles Louis Chrétien

Gilles-Louis Chrétien (5 February 1754 – 4 March 1811) was a French musician.

Chrétien was born at Versailles. In 1787 he invented a machine called a 'physionotrace,' with which he took portraits in profile from life, which were reduced to silhouettes, usually by Fouquet, and then engraved in aquatint by himself. Many of them are of great interest on account of the celebrity of the persons represented, 'L'Incorruptible Robespierre,' Mirabeau, and Marat being among the hundreds which he produced. Edme Quénedey was at first associated with him, but Chrétien afterwards worked alone. He died in Paris in 1811.
