Pasteur, Louis (1822-95). Signed portrait photograph of Pasteur in middle age, by A[lphonse] Liébert (1827-1914). Paris, n.d. (1879 or later). 93 x 62 mm., mounted on printed card measuring 106 x 64 mm. Pasteur's signature ("L. Pasteur") at the foot of the card. Very fine.
Excellent signed photograph of Pasteur. Signed photographs of Pasteur are very rare. Photographs that are advertised as signed often contain printed signatures. This is the first authentic autographed photograph of Pasteur that we have handled in forty years. The verso of the mount is printed with an advertisement for Liébert's "Photographie faite la nuit"; i.e. photographs taken with artificial electric light. Liébert began advertising this service in 1879. He spent some time in the American West. See Palmquist and Kailbourn, Pioneer Photographers of the Far West , pp. 369-370).Book Id: 42205
