According to many photography historians, Rahmizâde Béhâeddin was the first Turkish Muslim photographer. His photographs, especially portraits, are of such artistic depth and quality that qualify as reference in the documentation of his period at the places he lived - Turkey and Crete. He was born on 19 June 1875 in İstanbul to the wealthy Turkish family of İbrahim Rahmi Giridi Efendidir living in Crete. At his hometown Η ania, Crete, he graduated from secondary education in 1886 and then enrolled at Galatasaray High School (Mekteb-i Sultanî, at that time), Istanbul, graduating in 1895. The following year he returned to Η ania and operated a paperwork business until 1907, almost simultaneously with Hanyalı Salihzade Salih Zeki who initiated him in photography. He s ettled in this profession in İzmir and İstanbul between 1910-1915, and founded the 'Resna' photo studio, which was led by Resneli Niyazi. Considered one of the turning points in Turkish history, the 'Resna' studio operated near the Sublime Porte Street at the Pera district (Beyoğlu) and competed with established photographers at this address. Béhâeddin played a major role in the upbringing of young masters of photography (Prevezeli Mustafa Neset and the Cretan Hamza Rustem). Béhâeddin moved to Ankara in 1935, opened the "Otopus" photo studio in 1937 and was appointed Manager of the Turkish Historical Society photography department. He died in 1951 in Istanbul.
