More About the Presenter
Oscar (Osi) Sladek was born in Czechoslovakia in 1935. In 1938, Slovakia seceded from Czechoslovakia and aligned with Nazi Germany, initiating an era of widespread persecution and oppression of Jewish citizens. As Jews were systematically targeted, arrested and killed, Osi’s family survived by living in hiding and posing as Gentiles. When the search for Jews intensified, the family fled to the mountains, where they endured extreme conditions with minimal food and shelter until their liberation by the Russian army in 1945.

In 1949, Osi and his family immigrated to Israel, and he later settled in the United States. Today, he speaks to schools and organizations, sharing his firsthand account of survival and resilience. Despite living in constant fear during the Holocaust, Osi never lost his faith. His message emphasizes the triumph of good over evil, reminding audiences, “Goodness goes much further than evil in life. Never lose faith. Go on and live a good life.”
