Of Armenian descent, Agop Dilâçar was born Hagop Martayan in Constantinople in 1895. His father was Vahan Martayan and his mother Eugenie Martayan. He studied English in the local American School editing the school's publication "School News". In 1910 he studied at the Robert College where he also learned German, Latin and Classical Greek, graduating from Robert College in 1915. After completing his studies, he served as an officer in the Ottoman Army's Second Division in Diyarbakır. He was awarded for his bravery and continued serving in the Ottoman Army reserves. Because of his knowledge of English, he worked as a Turkish Army interpreter for the British prisoners of war held after the Siege of Kut south of Baghdad. He was arrested and escorted to Damascus for alleged secret extrajudicial contacts with the British prisoners. In Damascus, he was introduced for the first time to Mustafa Kemal Pasha. Mustafa Kemal Pasha was then the Commander of the Ottoman Army's Seventh Division. Mustafa Kemal was impressed by Martayan's intelligence and secured a pardon for him and took him into his headquarters. In 1918, Martayan moved to Lebanon, where he became the headmaster of Beirut's Sourp Nshan Armenian National School. In Lebanon, he established Louys, an Armenian periodical. In 1919, he returned to Istanbul where he worked as a lecturer of English at the Robert College. In 1922, he married Méliné Martayan and the couple moved to Bulgaria where he taught Ottoman Turkish and ancient East languages at Sofia University in Sofia, Bulgaria. In Sofia he also published the Armenian weekly Mshagouyt and the monthly Armenian periodical Rahvira. He published a study of Turkish language in Istanbul's Arevelk. A translated copy of the article gained the attention of Mustafa Kemal Pasha who invited him to return to Turkey where he lectured in Faculty of Languages, History and Geography. On September 22, 1932, he was invited as a linguist to the First Turkish Language Congress held in Dolmabahçe Palace supervised by Atatürk, the founder and first president of the Republic of Turkey, together with two other linguists of Armenian ethnicity, İstepan Gurdikyan and Kevork Simkeşyan. He continued his work and research on the Turkish language as the head specialist and Secretary General of the newly founded Turkish Language Association in Ankara. Following the issue of the Law on Family Names in 1934, Mustafa Kemal Pasha suggested him the surname Dilaçar, which he gladly accepted. Nevertheless, he continued to use the surname Martayan to sign his articles in the Armenian language. In return, Agop Martayan openly proposed the name Atatürk to Mustafa Kemal Pasha in the Grand National Assembly of Turkey. He taught history and language at Ankara University between 1936 and 1951. He also was the head adviser of the Türk Ansiklopedisi, between 1942 and 1960. He held his position and continued his research in linguistics at the Turkish Language Association until his death on 12 September 1979, in Istanbul.
Armenian publications
In addition to his work in Turkish language, he also published in Istanbul's Armenian media, in particular with the Armenian daily Marmara. In 1922, he published his literary workAratchin Portsutyun. Also in 1922, he translated Armenian playwright Levon Shant's play Hin Asdvadzner to English. In 1929 he published his Armenological study "Kri Dzakoume yev Daradzoume" and in 1929 "Hapetapanoutyun" in addition to an Armenian translation of a collection of English poetry under the title Albyoni Bardezen also in 1929. In 1951, he published his book Hazar Hink Harur Amyagi Khoher. In 1956 he published his book Asdvadzashountche yev Ashkharhapare. He had numerous written works in linguistics, literature, studies and translations in Armenian. For example his literary work Salin Vra , a collection of poems Khonchadz Yerazner, a theatrical piece Tsaykatiter and studies like "Levon Shant, Ir Pilisopayoutyune yev Kegharvesde" and "Hay Tyutsaznavebe, Pakhtadadagan Himi Vera".
After his death in 1979, in a news coverage, the then only Turkish TV channel TRT concealed the first name "Agop", which would suggest an Armenian descent, and instead mentioned "A. Dilaçar", using only the initial of his forename together with his surname. TRT was criticized for this attitude and the question was raised, if one is ashamed to mention the full name of one of the most important scholars of the Turkish language and thus reveal his Armenian descent.
Controversy
According to a rumor, he was the person who officially proposed the surname Atatürk to the founder of Turkey, Mustafa Kemal Pasha. In fact, President of the Turkish Language Association Saffet Arıkan's "Ulu Önderimiz Ata Türk Mustafa Kemal" sentence in the opening speech of the 2nd Language Day on 26 September 1934 became an inspiration for surname Atatürk.
