The Polish Senate has posthumously honored World War II hero Jan Karski for his work in revealing details of the Nazi genocide taking place in Poland.

During a special meeting Feb. 15 of Upper House of the Polish Parliament, guests including U.S. Ambassador Lee Feinstein and Polish Foreign Minister Adam Daniel Rotfeld were briefed on the program to commemorate the centennial of Karski’s birth that will take place in 2014, Polish Radio reported.

In addition to special events, a monument will be erected in Warsaw in his memory, and a Warsaw street will be named after him.

Born Jan Kozielewski in Lodz, Karski adopted his nom-de-guerre after escaping from a German POW train and joining the resistance. Karski served as a courier between occupied Poland and the Polish government in exile.

After World War II, Karski settled in the United States and taught at Georgetown University until his death in 2000. — jta
