Dr. Samuel Drix was a physician and medical researcher in Lwow (Lvov), Poland, when Germany invaded in World War II. He lost all his family to the Nazi Holocaust, including his wife Frania and two-year-old daughter Sylvia, and nearly all his friends. He survived the Janowska concentration camp, then escaped when the camp was closed and hid with the aid of a Polish farm couple. He worked as a successful doctor in Germany before emigrating to the USA in 1955, settling in New York City. He married again and had a son with his second wife Alice, also a survivor. Dr. Drix appeared as a witness in two war crimes trials in Germany; his 1977 testimony in Saarbrucken helped convict a notorious SS guard. In 1991, he was awarded the Order of Merit of the Federal Republic of Germany for his caring treatment of Holocaust survivors. He retired from private practice at the age of 80, and wrote a memoir, Witness to Annihilation (1994).
