French engineer, inventor, writer and engraver.
Achille Collas who developed a way of mechanically creating engravings after medallions and other reliefs, with a machine to copy sculptures at a smaller scale, the so-called "réduction mécanique", which popularized small sculptures and has been credited with being almost entirely responsible for "the transformation of the bronze industry".
He worked as an engineer before joining the Army at the end of the First French Empire. Afterwards he worked as a toolmaker and inventor. He never married. He applied for many patents, most of them for long-forgotten inventions for buckle-making machines and other tools. His most successful inventions was the reproduction of 3D artworks in 2D and 3D.
