Abdullah Frères (active 1870-1890s), three brothers who ran a commercial studio in Constantinople with branches in Cairo and Alexandria. In 1862, named official photographers to the court of Sultans Abdul Aziz and Abdul Hamid II, they were commissioned to document the Ottoman Empire. They also sold numerous views of Egypt and the Middle East to tourists. In 1899 they sold their business and archive to Sébah & Jollier (or Joaillier), which led subsequently to confusion of production from the two studios, since later prints from Abdullah Frères negatives are embossed with the Sébah & Jollier blind stamp.
