When he was just a baby Ralph Jacob (* 1939) emigrated to Holland with his parents due to Nazi persecution. In 1941, his father was deported to the Mauthausen concentration camp and murdered the same year. To escape the same fate, young Ralph was hidden by his mother with the help of resistance workers in the countryside. His mother went into hiding separately, and both survived the Nazi era. Later, Ralph Jacob worked as a representative for an international mining company in various countries, ultimately settling in Paris in 1990.
