In 1903, the Lumière brothers patented autochrome, the first technique for producing colour photographs.
Not long after the technology’s release, Albert Kahn, a Franco-Jewish financier-turned-philanthropist, set about creating a photographic record of the entire world. He sent photographers to every continent, and they returned with reels of film and photographs. By the end of Kahn’s project in 1931, he had amassed 180,000 metres of film and more than 72,000 autochrome photographic plates. He called the collection ‘Archives of the Planet’.
