INGRAM, JOHN (1721–1771?), engraver, born in London in 1721, first practised engraving there. He subsequently went to Paris, and settled there for the remainder of his life. He both etched and engraved in line-manner. He engraved a number of plates after François Boucher, some after C. N. Cochin, and a set of emblematical figures of the sciences in conjunction with Cochin and Tardieu. He was employed in engraving small plates for book illustration, and more especially on plates for the ‘Transactions’ of the Académie des Sciences. He was an engraver of great merit.
