Alphonse Justin Liébert (30 November 1826, Tournai - 18 June 1913, Paris) was a French photographer.
Initially devoted to a career in the Navy, he was wounded at the Battle of Vuelta de Obligado (1845), in Argentina.
They had three children; Marie-Louise, apparently born out of wedlock, Gaston Ernest, a career diplomat, and Georges Auguste (1876-1947), who also became a photographer.
[3] He was one of the few photographers to remain in Paris during the Commune; documenting the buildings destroyed during the Bloody Week, and the barricades built by the Communards.
In 1897, together with his son, Georges, he founded "A. Liébert et Cie", devoted to the manufacture and distribution of silver celluloid photographic paper.
