French painter and engraver chiefly remembered for his portrait engravings, which were cut exclusively with a graver, or burin. Masson's portrait of “The Grey-Headed Man” and his “Christ with the Disciples at Emmaus” are examples of his finest work.

Masson was reared to be an armourer and learned to engrave ornamental designs on steel. He settled in Paris while still a young man, took up drawing, and gained a reputation in portraiture. He soon devoted himself to engraving, became noted for his grand-style prints, and in 1679 was made a member of the Academy in Paris.
