Biography
Achille Collas (1795–1859) was a French engineer, inventor, writer, and engraver from Paris who changed the way art was reproduced in 19th-century Europe. He is mainly known for creating two mechanical processes: one for making engravings from medallions, cameos, and other relief objects, and another for making smaller three-dimensional copies of sculptures. These inventions changed how art was made, distributed, and enjoyed by a growing middle-class audience looking for affordable cultural items.
Collas started his career as an engineer before joining the Army near the end of the First French Empire. After his military service, he focused on toolmaking and inventing, applying for many patents across a range of mechanical devices like buckle-making machines. Most of his early inventions didn't last, but they did build his reputation as a prolific inventor interested in precision machinery.
His first major impact on the art world was a mechanical way to create engravings from cameos, medals, and relief sculptures. He developed this method between 1825 and 1832, and it was first shown at the Salon of 1833, gaining a lot of attention. Collas used this technique for the illustrations in Henry Fothergill Chorley's The Authors of England (1838), a book featuring medallion portraits of British literary figures. He ambitiously applied this method to create the Trésor de numismatique et glyptique, a significant work completed in 1850 that reproduced around 15,000 numismatic and glyptic objects across 20 volumes.
In 1836, Collas invented a pantograph-like machine that could reproduce sculptures at smaller scales and in different materials like plaster, wood, ivory, and bronze. Two years later, he teamed up with entrepreneur Ferdinand Barbedienne to start the Société Collas et Barbedienne, a company focused on producing and selling these scaled reproductions. Their first product was a smaller copy of the Venus de Milo. Although the business grew slowly at first, it gained significant international recognition when Barbedienne showcased pieces at the Great Exhibition of 1851 in London, after which demand increased greatly. The company's work is credited with almost entirely transforming the French bronze industry in the second half of the 19th century.
Collas remained unmarried and spent much of his life on his inventions and intellectual activities. He died in Paris in 1859, leaving behind work that went beyond mechanical interest to have lasting commercial and cultural impact.
Before Fame
Achille Collas was born in Paris in 1795, a time of great political and social change in France after the Revolution. He trained as an engineer, a profession that was becoming more respected and important during the early industrial age. He took a break from his engineering career to join the French Army towards the end of Napoleon's First Empire, which gave him insights into the organizational and material needs of large institutions.
After his military service, Collas returned to civilian life as a toolmaker, using his technical skills to invent new devices. He pursued patents for various mechanical equipment, mostly related to everyday industrial tools like buckle-making machines. Although this period wasn't very commercially successful, it improved his knowledge of precision engineering and set the stage for his more culturally important inventions later on.
Key Achievements
- Developed a mechanical process for creating engravings from medals, cameos, and relief sculptures, demonstrated publicly at the Salon of 1833
- Produced the Trésor de numismatique et glyptique, a 20-volume work reproducing approximately 15,000 numismatic and glyptic objects, completed in 1850
- Invented a pantograph-like machine in 1836 capable of reproducing sculptures at reduced scales in materials including bronze, ivory, plaster, and wood
- Co-founded the Société Collas et Barbedienne in 1838 with Ferdinand Barbedienne, a company credited with transforming the French bronze industry
- Created the medallion portrait illustrations for Henry Fothergill Chorley's The Authors of England (1838), introducing his mechanical engraving process to an international readership
Did You Know?
- 01.The Trésor de numismatique et glyptique, which Collas produced using his mechanical engraving method, spanned 20 volumes and reproduced approximately 15,000 individual numismatic and glyptic objects when completed in 1850.
- 02.Collas never married and appears to have dedicated his personal life almost entirely to his inventions and technical projects.
- 03.The first product sold by the Société Collas et Barbedienne was a mechanically reduced reproduction of the Venus de Milo, making one of antiquity's most celebrated sculptures accessible to buyers who could not afford or acquire the original.
- 04.Collas's partnership with Ferdinand Barbedienne began in 1838, but the company only achieved wide international recognition after Barbedienne exhibited their reduced sculptures at the Great Exhibition of London in 1851.
- 05.Most of Collas's early patents were for long-forgotten industrial tools such as buckle-making machines, none of which achieved the commercial or cultural impact of his later art-reproduction inventions.
