Jaffe, Friedrich, 1903-

The Else Richthofen-Jaffé Correspondence primarily consists of the family correspondence of this social scientist. Much of the collection consists of Else Richthofen-Jaffé's correspondence with her adult children and their families, although some correspondence with other family members or other close individuals is also present. In addition the collection contains parts of an unpublished work on the family and some genealogical notes.

The Frieda Lawrence Letters hold some letters of Frieda Lawrence primarily sent to her sister Else Richthofen-Jaffé and Else's son Friedel Jaffé. Included in the first folder of the collection is a summary of the letters by Guenther Roth, which also provides context for them and biographical details on Frieda Lawrence.
