Jan Karski (born Jan Kozielewski, 24 June 1914 – 13 July 2000) was a Polish soldier, resistance-fighter, and diplomat during World War II. He is known for having acted as a courier in 1940–1943 to the Polish government-in-exile and to Poland's Western Allies about the situation in German-occupied Poland. He reported about the state of Poland, its many competing resistance factions, and also about Germany's destruction of the Warsaw Ghetto and its operation of extermination camps on Polish soil that were murdering Jews, Poles, and others. Emigrating to the United States after the war, Karski completed a doctorate and taught for decades at Georgetown University in international relations and Polish history. Read more on Wikipedia
