14 gen 1782 anni - 1782 LE PRINCE Jean-Baptiste Aquatint is invented

Descrizione:

There are various claimants to the role of inventor of the "Aquatint" including

the Sweden Per Floding working with the Frenchman François-Philippe Charpentier in 1761

J. B. Delafosse in 1766, working with the amateur Jean-Claude Richard (often rather misleadingly known as the Abbé de Saint-Non)

in 1766, and Jean-Baptiste Le Prince in 1768-69.

Le Prince was more effective than the others in publicizing his technique, publishing "Découverte du procédé de graver au lavis" in 1780, though he failed to sell his secret in his lifetime.

It was bought posthumously by the Académie royale de peinture et de sculpture in 1782, who released it on an open basis
