4 year old Joseph Schleifstein, who survived the Holocaust by being kept hidden by his father, from Nazi officials inside Buchenwald concentration camp, is seen here shortly after his liberation in April, 1945

Joseph Schleifstein (born March 7, 1941) is a Polish-born American who survived Buchenwald concentration camp at the age of four, one of the youngest to survive the Holocaust. He was hidden by his father in a large sack, enabling him to avoid detection by SS guards when arriving at the camp. Other prisoners helped his father keep him hidden and Schleifstein survived until the Americans liberated the camp. After the war, Schleifstein and his parents emigrated to the United States. He did not discuss his wartime experiences for decades, even with his children. His case was discovered by chance in 1999, leading to a search for him and an eventual newspaper interview.
