István Kertész (later known as Stephen Denis Kertesz) (April 8, 1904–January 26, 1986) was a Hungarian diplomat who represented Hungary during the peace talks following World War II.
He was born on April 8, 1904, in Putnok, Hungary, to Lajos and Mária (Stolcz) Kertesz.[1] He received a Dr. Jur. from the University of Budapest in 1926, and a diploma from the Institut des Hautes Etudes Internationales in Paris in 1928.[2] During the Second World War, worked in the Hungarian Ministry of Foreign Affairs, and in 1943-1944, made efforts to convey the intentions of Admiral Miklós Horthy to surrender to the Allied powers in order to avoid further damage to the country.
After the war, Kertész opposed the Soviet takeover of Hungary and tried to avert the Allied demand to expel the German minority from Hungary. In 1946, Kertész represented the Hungarian government at the Paris Peace Conference.
Later, he fled Hungary and emigrated to the United States, where he lectured on diplomacy and international relations.
