In page Hippolyte Arnoux:

"

Arnoux is known to have established a studio in Place de Consuls in Port Said in the 1860s, and later a different studio at Place Ferdinand de Lesseps also in Port Said. [4] He also operated a floating darkroom in Port Said in the 1860s and 70s, of which a photograph survives. [5] He may have been the official photographer, appointed by the Universal Company of the Suez Canal, to document the work on the canal. In this capacity, Arnoux may have hired the Zangaki Brothers to assist him. [6] At a later date, Arnoux was in partnership with the British-Italian photographer, Antonio Beato. [7]
