A Jewish resident of Haarlem. Prior to the war, Corrie and Father frequently encounter the man walking his beloved bulldogs. During the occupation, when they see that he has a yellow star sewn onto his coat, they befriend him. Harry has converted to Christianity but retains his Jewish cultural identity, and he and his wife Cato become regular visitors at the Beje. Eventually, fearing imminent deportation, they seek help with the ten Booms and Corrie places them in a safe house. However, eventually the house is raided by the Gestapo. Harry is deported and Corrie never discovers what happens to him.
