Willem ten Boom started a watchmaking shop in 1837. After he died, his son Casper took over the business and the house, where he lived with his daughters Betsie and Corrie. When World War II broke out, they helped hundreds of Jews and other refugees by hiding them in their home. On 28 February 944, the housed was raided and 30 people were arrested. Casper ten Boom died in the prison of Scheveningen. Betsie died in camp Ravensbrück. Corrie survived the war and became an evangelist.
