Philippe Danfrie

Philippe Danfrie the elder (about 1532 in Cornouaille in Brittany - 1606 in Paris), was a designer and maker of mathematical instruments in metal and paper, as well as a type-cutter, engraver, minter of coins and medals, publisher and author. Much is known about Danfrie's life and activities. He is probably best known as designer of the surveying instrument known as the graphometer.

Danfrie went to Paris in the 1550s and set up as an engraver of letter punches. He produced a number of books in partnership with Richard Breton in 1558–60 and later with Pierre Haman and Jean Le Royer. He also made mathematical instruments, globes and astrolabes and dies for marking bookbindings. In 1571 he cut his first dies for jetons. As Engraver-General of the French coinage from 1582, he provided the puncheons from which the dies used in every mint in France were taken. He also produced a number of medals (e.g. London, BM) commemorating the events of the first fifteen years of Henry IV’s reign.
