The Rolf Ransenberg papers consists of the correspondence from the Ransenberg family to their son Rolf, who was in the United States. The letters are personal in nature, and often contain notes from everyone in the family, including all of the other children, since Rolf was the oldest. They range in length from shorter notes to longer letters, but are nonetheless frequent and consistent throughout the period from 1938-1941. In addition to the letters, there are also some personal documents that belonged to Rolf and Friedel Ransenberg, including paperwork regarding Rolf's service in the U.S. Army during World War II.
