Magnificent vintage matte-finish 17.75 x 20.75 portrait photo of Louis Pasteur, as taken by Pierre Petit in 1886, printed by Chardon & Sormani, signed and inscribed in the lower border in fountain pen, “Très affectueux souvenir à mon confrère A: Gautier, L. Pasteur,” whose facsimile signature is present to the right. In very good to fine condition, with small stains touching the signature, and other stains, tears, and edge wear constrained primarily to the borders. Photographs signed by Pasteur remain rare and highly sought-after, with this oversized example, which boasts a remarkably clear portrait of the pioneering microbiologist, perhaps the most impressive that we have ever offered.
