"The Ruth Oppenheimer letters contain correspondence collected by Oppenheimer during her time living in Nazi-era Germany. The bulk of the correspondence comes from her boyfriend George Rau to Oppenheimer, during his imprisonment in 1939. George was arrested for having a relationship with an Aryan woman, and was later tried and found guilty of the same crime before dying in prison. The letters were written weekly and sent to Ruth. In addition are a letter and postcard from Rau prior to 1939, and correspondence from Rau’s family after his death."@eng . . . .
