Dr. Janusz Korczak was a writer who directed an orphanage in Warsaw and as the Warsaw Ghetto was being liquidated, he personally led his orphans to their deaths in the Treblinka death camp in 1942.

 Dr. Ludwig Zamenhof invented a new language, “Esperanto,” so that everyone, regardless of native tongue, might be able to communicate with one another and get along better.  Nowadays two million people in about 100 countries speak Esperanto.

Dr. Emmanuel Ringelblum was the eyewitness historian who documented the Jewish resistance against the Germans in the Warsaw Ghetto, which began on April 19, 1943.  His records were undeniable proof of the German atrocity against the ghetto Jews and were hidden in three milk cans so that the memory of the doomed community would endure.  Of the two cans found, one is on display at the U.S. Holocaust Memorial Museum in D.C.
