Marking a milestone in the history of Turkish gynecology, Huseyin Nasid Erez was born on 14 June 1899 in Istanbul. After graduating from the Lausanne University Faculty of Medicine in 1924, he returned to Turkey and soon was assigned as an assistant at the Clinic of Gynecology and Obstetrics at the Istanbul University Faculty of Medicine. Dr. Erez founded the second Clinic of Gynecology and Obstetrics at the same university in 1942. He was promoted to professorship in 1944, then to ordinarius (senior) professorship in 1957. After the military coup of May 27th 1960, he was discharged from the university together with 146 other academics; after two years, however, he was restored to his previous workplace, from where he would retire in 1969. Following the footsteps of his tutor Ord. Prof. Dr. Wilhelm Gustav Liepmann (1878-1939), one of the originators of the social gynecology approach in the world, Dr. Erez greatly contributed by promoting, implementing and generalizing this approach in Turkey. He paved the way for developing a national family planning program and promoting contraception practices in Turkey. He also pioneered using medical movies in gynecology education and at scientific meetings. In the field of medicine, he published three books and 48 articles, and translated a book from German. Dr. Nasid Erez died on December 21th 1981 in Istanbul.
