Abdullah Frères was a photography studio in Constantinople (Istanbul), one of the most successful and famed during the late Ottoman Empire.
It was run by three brothers of Armenian heritage - Viçen Abdullahyan (1820–1902) (later known as Abdullah Şükrü after converting to Islam), Hovsep Abdullahyan (1830–1908) and Kevork Abdullahyan (1839–1918).
Over 40 years, the Abdullah brothers took many portraits of different types of people, landscapes, architecture, but also documented various political and social events, historical and cultural values.
The studio existed from the 1850s until the early 1900s. In 1863, the Abdullah Frères were appointed he official court photographers by Sultan Abdulaziz. From 1866 to 1895, the brothers also ran a studio in Cairo, Egypt.
