István Kertész (1904-1986) was a Hungarian diplomat who represented Hungary during the peace talks following World War II.
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 take over 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 from Hungary and immigrated to the United States, where he lectured on diplomacy and international relations.
