Cornelia Arnolda Johanna "Corrie" ten Boom (15 April 1892 – 15 April 1983) was a Dutch watchmaker and later a Christian writer and public speaker, who worked with her father, her sister and other family members to help many Jewish people escape from the Nazis during the holocaust in World War II by hiding them in her home. They were caught, and she was arrested and sent to the Ravensbrück concentration camp. Her most famous book, The Hiding Place, is a biography that recounts the story of her family's efforts and how she found and shared hope in God while she was imprisoned at the concentration camp.
