He is probably the sculptor Jean-Abraham Chevalier, who was born in 1760 or 1761 in La Rochelle. He was the student of Martin Monot when he enrolled, 14 April 1781, at the school of the Académie royale de peinture et de sculpture in Paris, where he studied until Spring 1782. Groce and Wallace mention him under the name of Abraham Chevalier and affirm that he worked in Baltimore (MD) from 1805 to 1825 app., then in Philadelphia. His works can be found at the Maryland Historical Society.
