Anita Schorr, 83, of Westport, is a Holocaust survivor. On Tuesday, she visited Vinal Technical High School in Middletown, to share her story. Born in Czechoslovakia, she is the only member of her family to have survived the Nazi’s attempt to obliterate the Jews. At age 13, she was sent to Auschwitz concentration camp and later to Bergen-Belsen, from which she was liberated in 1945. After emigrating to the U.S. in 1959, she remained silent about her experiences for many years. But a visit to the Holocaust Museum in Washington D.C. when it opened 20 years ago changed her. She could no longer keep silent. Since then, Schorr has spoken to hundreds of groups in Connecticut and New York about her experiences. Her goal is to teach people to not stand by when atrocities occur. “The free world stood silent,” while the Holocaust unfolded, she said. She hopes it never happens again.
