Robert Felder (born Rudi Dingfelder) is the son of Leopold and Johanna Dingfelder. He was born April 21, 1924 in Uehlfeld, Germany, but grew up in Plauen, where his father ran a kosher butcher shop. Rudi had one older brother, Martin, who immigrated to the United States in 1938. The following year Rudi and his parents booked passage on the MS St. Louis. When the ship returned to Europe the Dingfelders disembarked in the Netherlands. In 1942 Rudi and his parents were arrested in Gouda and sent to the Westerbork transit camp. His parents were subsequently deported to Auschwitz, where they perished. Rudi, who had stayed behind in the transit camp, was later transferred to Vught and then back again to Westerbork. In March 1944 he, too, was deported to Auschwitz. Rudi was one of only 55 members of his convoy of 2500 people to survive the initial selection at the camp. In January 1945 when Auschwitz was evacuated, Rudi was put on a death march to Germany. He was taken first to Buchenwald and later transferred to Oranienburg. A trained toolmaker, Rudi was assigned work at Siemensstadt-Sachsenhausen, was later moved to Siemensstadt-Berlin, and finally, was sent to a factory camp near Schwerin. In the closing weeks of the war he managed to escape from Schwerin and was liberated by a group of American soldiers a short time later. After the war Rudi returned to Gouda, where he met his future wife, Gerry, the daughter of a Jewish father and a non-Jewish mother. In March 1947 Rudi joined his brother in the United States, leaving Gerry behind temporarily. She joined him in 1948, and they were married soon after. Rudi and Gerry settled in Detroit, where their daughter, Joan, was born. Rudi Dingfelder died in Detroit in 1986.
