(AP) — The CBS newsmagazine 60 Minutes aired a powerful report Sunday night on three of the Holocaust’s youngest known survivors — all born in the final weeks of World War II to mothers who hid their pregnancies while imprisoned by the Nazis.

The broadcast recounted the extraordinary stories of Eva Clarke, Hana Berger-Moran, and Mark Olsky, now 80, who were born in April 1945 as Nazi Germany was collapsing.

Each of their mothers became pregnant in 1944 and was deported to Auschwitz, where pregnancy meant almost certain execution. By concealing their conditions beneath loose prison garments and avoiding detection by guards, the women managed to survive long enough to be transferred to labor camps inside Germany.

As Allied forces closed in, prisoners were forced onto transports in brutal conditions. One of the babies was born during a grueling train journey. Another entered the world in a labor camp just days before liberation at Mauthausen.

The program detailed how American troops discovered starving prisoners and newborn infants when they liberated the camp in early May 1945. In one case, a U.S. Army medic helped keep a newborn alive in the chaotic aftermath.

Now octogenarians living in different countries, Clarke, Berger-Moran and Olsky have connected later in life, describing a bond forged by shared origins in one of history’s darkest chapters. Their survival — and that of their mothers — stands in stark contrast to the Nazis’ systematic attempt to eradicate Jewish families across Europe.
