Gilles Demarteau

Gilles Demarteau or Gilles Demarteau the Elder (Liège, 19 January 1722 – Paris, 31 July 1776) was an etcher, engraver and publisher who was active in Paris for his entire career. He is one of the persons to whom has been attributed the invention of the crayon manner of engraving. He is recognized as playing an important role in the development of this engraving technique. He was one of the key reproductive engravers and publishers of the work of François Boucher.

Gilles Demarteau was born in Liège, at the time in the Prince-Bishopric of Liège (now Belgium). His father was a gunsmith, from whom Demarteau learned metal engraving and the goldsmith's trade. He likely also studied drawing as he became one of the best draftsmen of his time. Still young, he joined in Paris his brother who worked there as a goldsmith. This was probably around 1748-1750. His brother worked for the Parisian engraver De Lacollombe, who is known chiefly for his designs and engravings of firearms ornaments. Gilles also joined the workshop of De Lacollombe as a 'graveur-ciseleur'. In this capacity he not simply worked as an engraver of prints but also trained to decorate metal objects, in particular goldsmiths' work.

In 1746 at the age of 24, he was admitted as a master engraver-carver on all metals. His first known works date to the mid 1740s and consist of sheets of ornaments engraved with chisels for decoration rifles, pistols or snuff.

In 1755 he settled permanently in the rue de la Pelleterie, near the Royal Palace. Here he lived until his death. He also founded his own engraving workshop in the Rue de la Pelleterie, which operated his workshop under the shop sign 'à la Cloche'.

Gilles Demarteau used in 1756 goldsmith's chasing tools and marking-wheels to shade the lines in a series of Trophies designed by Antoine Watteau. Jean-Charles François who was a partner of Demarteau further developed the technique further and used it to engrave the whole plate. François engraved in 1757 three etchings directly on copper in crayon manner. He then used the technique to etch three plates using different-size needles bound together. Other people who contributed to this new engraving technique included Alexis Magny and Jean-Baptiste Delafosse. François and Demarteau separated ways in 1757 over conflicts relating to who was entitled to call himself the inventor of the new technique. In 1759 Demarteau was joined in his studio by Louis-Marin Bonnet, a former pupil and collaborator of François. Bonnet engraved in that same year his first plate for Demarteau.
