François Willème (1830-1905) pioneered an innovative technique of 3D modeling he termed "photosculpture" in 1859. This process used early photographic methods coupled with a pantograph mechanism to capture and replicate the forms of living subjects with unprecedented speed and accuracy compared to conventional sculpture.
Willème‘s fame and patronage soared in the early 1860s as royalty, celebrities, and high society sought out his technology to obtain perfect likenesses relatively cheaply. However, declining interest saw his once prosperous business falter by the late 1860s, though his concepts presaged key developments in 3D scanning and modeling.
Apprenticeship and Artistic Influences
Born in Sedan in 1830, Auguste François Willème honed his innate creative talents through rigorous artistic instruction during his youth. His early promise at drawing earned him enrollment at the acclaimed École des Beaux-Arts in Paris under the tutelage of renowned painter Henri Philippoteaux.
As part of his diversified training, Willème cultivated skills in sculpture, casting, and metalworking while producing commissioned bronzes and objets d‘art for Parisian manufacturers. He exhibited a natural facility with translating life into three-dimensional mediums. Simultaneously, Willème remained an avid painter, with several canvases accepted into the annual Paris Salon exhibitions.
During this period, Willème became increasingly fascinated with the relatively new medium of photography, particularly in rendering detailed sculptures and figures. The pioneering photographer Nadar, a contemporary of Willème, had utilized early daguerreotype processes in the 1840s-50s to capture uncannily lifelike portraits. Willème saw immense potential for photography to revolutionize sculpture production.
Invention of Photosculpture Process
By 1859, Willème had developed an invention he named "sculpture photographique", known in English as photosculpture. This revolutionary technique combined early wet-plate photographic methods with automated reproduction via a pantograph apparatus to create nearly identical 3D sculptures of subjects rapidly and inexpensively compared to traditional statuary production.
The 24-Camera Capture Rig
The complex process centered around a dedicated rig, conceived and constructed by Willème, to perform 360-degree photographic captures. His Paris studio contained a large central platform, brightly illuminated by an overhead glass cupola and periphery gas lamps emitting a luminous 30,000 lux.
The subject would mount the slightly-elevated rotating dais, surrounded by a concentric ring hosting 24 synchronized cameras at 15-degree intervals. By triggering via wires, Willème could operate the shutter on each camera nearly simultaneously to record the person‘s silhouette from all angles within a fraction of a second.
This established a complete visual profile record of the subject with sufficient resolution to discern fine features and textures. Willème had essentially invented an early form of 3D scanning.
Prototype Fabrication Apparatus
With profile photographs from 24 optimally spaced perspectives, Willème had captured the comprehensive volumetric data needed to reconstruct his subject. But generating a sculpture still demanded numerous manual operations.
To expedite production, he devised an automated pantograph-guided routing apparatus. Willème created projection slides of the 24 negative films, corresponding to angular "slices" through the subject. By sequentially projecting each enlarged profile onto a tracing screen, Willème could reproduce their outlines to life-size scale via the pantograph‘s twin tracer needles.
Through an ingenious system of adjustable arms and shafts, the second needle precisely directed a rotary cutter over restless blocks, carving each traced contour. Adjusting layers vertically after cutting then enabled assembly of a rough 3D relief map of the subject. This concluded the automated phase, after which traditional sculpting skills finished facial details and surface textures.
According to Willème‘s patents, this photosculpture technique reduced production costs by nearly 90% compared to conventional sculpture. Hand carving and casting a bust took months and commanded fees around 500 francs – but expanding his pantograph outputs to scale yielded equivalent results in under a week for just 50 francs.
Establishing the Photosculpture Business
In 1860, Willème filed patents in France for his photosculpture technique and established a corporation to commercialize the invention. One notable early investor was Isaac Péreire, a prominent banker who was the grandson of Jacob Rodrigues Pereire, creator of the pioneering Pereire Calculating Machine in the 18th century.
Willème spent the next few years honing the process before unveiling his opulent new photography studio in April 1863. Located at 42 Boulevard de l’Étoile near Paris‘ Arc de Triomphe, the facility featured a soaring 40-foot rotunda with a cupola of iron beams and blue-tinted glass to optimize lighting. The space easily accommodated his custom 24-camera photo capture rig plus prototype fabrication apparatus.
Noteworthy Early Patrons
Word of the novel technology spread rapidly as Willème produced uncannily accurate busts, statuettes, and portraits of French nobility, artists, and literati in a fraction of the time traditional sculpture required. The imperial couple Napoleon III and Empress Eugénie became notable patrons, even hosting receptions at the Louvre and Compiègne Palace to showcase Willème‘s latest sculpted dignitaries.
The writers Alexandre Dumas and Théophile Gautier extolled this new "magical art" that could replicate an individual down to the finest details in only days. Composer Gioachino Rossini was also an early subject, with photosculpture allowing him to gift highly accurate portrait busts to other European musician friends.
By early 1865, competing photosculpture studios had opened in London to serve British aristocracy and luminaries like Charles Dickens. The following year saw one established in New York under Frederick Behrens as American elites like Vanderbilts and Astors clamored for their own sculptures.
Presentation at the Paris Exposition Universelle
The photosculpture craze reached its zenith in 1867 when Willème unveiled dozens of his portrait busts and statuettes at that year‘s Exposition Universelle arts and industry fair in Paris. His technical capabilities earned accolades from the judges while curious crowds thronged the pavilion daily to witness demonstrations of the automated photo-scanning and pantograph carving process.
Contemporary accounts relate that Willème conducted over 300 individual sculpture sessions that summer to meet demand, including duplicates for customers wanting works cast in different materials like plaster, clay, terra cotta, or bronze. But this flood of business was not to last.
Decline of Popularity
While the elite appreciated the speed and accuracy of photosculpture initially, some critics increasingly assailed the cold perfection as lacking artistic style or interpretation. The identical statues seemed soulless repetitions that failed to flatter their subjects. Enthusiasm also waned after nearly everyone fashionable had obtained their own busts and photography‘s novelty faded.
Financial issues compounded the situation as maintaining Willème‘s large Paris studio with its specialized equipment and staff proved costly. As commissions slowed over the next year, he tried cost-cutting measures but was ultimately forced into bankruptcy. In 1868, Willème sold the landmark photosculpture studio and returned with his family to his hometown of Sedan.
Revenue figures from the Paris photosculpture operation reveal the dramatic reversal of fortunes. In 1865, at the height of popularity, weekly income averaged around 5,000 francs with a 30% profit margin. Yet by late 1867, total monthly revenue had dropped to only 1,200 francs with the business losing money on every sculpture sold.
Later Rediscovery and Legacy
Back in Sedan, Willème partnered with a local photography studio for several years, producing portraits and sculpture using his method on a smaller scale. During this time he continued to refine the photosculpture technique, receiving French patents in 1876 and 1882 for mechanical improvements, including substituting a helical tracing movement for the pantograph.
Some references state he gave art lessons later at the Collège Turenne while continuing sculpture work using photosculpture up to the 1890s. Ever the inventor, Willème did obtain additional photosculpture patents over the next decades for techniques to streamline production, but widespread adoption never returned.
His one-time Paris studio struggled on for a period under new ownership, catering to remaining elite interest through the early 1870s before conversion into a dance hall venue spelled the impending end. However, photosculpture did see brief resurgences, such as an 1900 system by Italian engineer Carlo Baese who used photo-sensitive gels that expanded when exposed to light in order to form more automated portraits based on lighting exposures rather than routing.
Yet while his specific business implementation proved premature, Willème deserves recognition as a pioneering force in early 3D imaging and modeling. His ingenious fusion of contemporary photographic, illumination, tracing, mechanical, and material working principles prefigured critical facets of modern 3D data capture and computerized prototyping methods.
In the synchronized, multi-angle camera rig, we can discern an early structured light scanning apparatus not unlike those now used to map faces for CGI special effects. The automated carving via stacked relief projections similarly preceded by well over a century present techniques leveraging volumetric pixels and computer numeric control (CNC) mills. Photosculpture‘s ambitious scope situates Willème as a pivotal pioneer bridging art and emerging computation. One who pointed the way towards our current age of effortless digital reality replication.
