He was born in 1904 in Ayvalık (Κυδωνίες) in Asia Minor and died in Athens in 1973. He wrote many books throughout his career as an author. His most famous book is Number 31328.

During the Asia Minor Catastrophe he was 18 years old and was conscripted to a labour battalion of the Turkish State. In his book The Number 31328 - The Book of Slavery he describes the 14 months of his life that he had spent in a concentration camp, forced to hard labour.
