Who was the first Jew that the ten booms hid?

The first Jew that the Ten Boom family hid during World War II was a man named Hermann Sluring. The Ten Booms, a Dutch family, operated a secret room in their home in Haarlem, Netherlands, where they sheltered Jews escaping the Nazi regime. Hermann Sluring sought refuge with them early on, marking the beginning of their efforts to save many lives during the Holocaust. Their courageous actions were later chronicled in the book "The Hiding Place" by Corrie ten Boom.
