Jan Karski, born Jan Romuald Kozielewski in Łódź in 1914, acted as a vital courier for the Polish government-in-exile during the Second World War. His clandestine missions involved infiltrating German-occupied territory to document Nazi atrocities, providing the Western Allies with firsthand accounts of the Warsaw Ghetto and the operations of extermination camps located on Polish soil.
Early Career and War Service
Before the conflict, Karski completed his education at the University of Warsaw and Lviv University, subsequently joining the Polish Ministry of Foreign Affairs in 1939. Following the German invasion, his military unit was captured by the Red Army. He avoided the Katyn massacre by successfully concealing his officer rank. After escaping a transport, he reached Warsaw and joined the resistance movement, eventually becoming a member of the Armia Krajowa.

Tasked with reporting on the state of the resistance and German crimes, Karski entered the Warsaw Ghetto twice to witness the conditions of Jewish inhabitants. He later observed a transit camp for the Bełżec extermination site while disguised. These observations formed the basis of his reports to Allied leaders, detailing the systematic destruction and starvation occurring under German occupation. His efforts were instrumental in transmitting intelligence from the underground to government officials in Britain and the United States.
Post-War Academic Life
After the war, Karski emigrated to the United States and pursued an academic career. He earned a doctorate and spent decades teaching international relations and Polish history at Georgetown University. Although he remained largely silent about his wartime missions for many years, he eventually shared his experiences in interviews and the film Shoah in 1985. He authored the book Story of a Secret State and resided in Washington, D.C., until his death in 2000.
Awards and Legacy
Recognition for his wartime activities came primarily in his later years. In 1982, he was named Righteous Among the Nations, followed by the Jan Karski Courage to Care Award in 1988. He received honorary doctorates from Georgetown University, the University of Łódź, and Maria Curie-Skłodowska University. In 1994, he was granted honorary citizenship of Israel, and in 2012, he was posthumously awarded the Presidential Medal of Freedom.
