Louis Arthur Ducos du Hauron was born on December 8, 1837 in Langon, Aquitaine, France.
On March 1, 1864, Louis Arthur Ducos du Hauron patented, but did not build, a device for taking and projecting motion pictures. He was one of the first to conceive the three-color process of photography (and to actually produce a three-color print), for which he applied and received a patent from the French government on November 23, 1868. The physicist's theories formed the basis for later processes and had a tremendous influence on orthochromatic photography.
Louis Arthur Ducos du Hauron also developed a three-color camera which, using light filters, could simultaneously make three-color separations with one exposure. Called a "caméra héliochromatique," he received a patent for it in 1874, then patented a device for three-dimensional photography called an anaglyph in 1891. By 1897 Ducos du Hauron had invented a process for producing three-color negatives in a single exposure.
Louis Arthur Ducos du Hauron was also an accomplished pianist.
