English: L. Hill, cavalier chutant de son cheval (d’après peinture ou estampe), hillotype, 16,5 x 21,5 cm (pleine plaque), v. 1850-1855. Levi Hill of Westkill, NY, claimed for the first time to have invented a way to produce naturally colored daguerreotypes, or Hillotypes, as they became known. When Hill refused to release the details of his process until a patent was filed, the profession denounced him as a fraud. In 156 years, no definitive evidence has been presented to suggest that Hill was or was not an imposter, until now. Using state-of-the-art technology, the 62 Hillotypes acquired by the Smithsonian in 1933 from Hill's son-in-law, John Boggs Garrison, finally gave up their secrets. Examination of a number of the Hillotypes by GCI scientists and curators from the Smithsonian�s photography collection have confirmed that Hill was indeed a genius - he did discover a method to create several natural colors in his photographs.
