The Mauthausen Concentration Camp in German-occupied Austria was liberated on May 4, 1945. Among the more than 40,000 people rescued was Mark Olsky, who had been born just a few days before, in a cattle car en route to the camp.
With the camp's liberation, Olsky, his mother, and four of her siblings, survived the Holocaust - but just barely.
Olsky weighed only three pounds when he was born. His mother was under 70 pounds and was close to death.
