Pascal Sebah

From Getty's Early Photographers of Greece: Pascal J. Sébah (1823–1886), a Turkish citizen, owned El Chark (The Orient), one of the largest and most prolific photography studios in Constantinople (Istanbul). He made photographic excursions to Egypt and Greece in the 1870s, establishing another studio in Cairo in 1873. That same year the Turkish government sponsored his photographs at the Vienna International Exhibition and commissioned his Les costumes populaires de la Turquie en 1873. Upon his death Sebah's firm was taken over by his brother Cosimi. His nephew Jean joined the firm in 1890 and eventually went into partnership with Policarpe Joallier, changing the name to Sebah and Joailler.
