Professor D. O. Spettigue's Research Papers (Mss 57, 1985 & 1995, 16 Boxes) document the sensational discovery of the FPG identity in 1971. They also includethree German poems and two letters Thomas Mann sent to Grovefrom Princeton in 1939. – An additional Spettigue cluster was acquired in January 1995. It included Greve's correspondence with André Gide, Karl Wolfskehl, O. A. H. Schmitz, and contained materials related to the English translation of Greve's 1905 novel "Fanny Essler." – Thanks to professors Spettigue and Hjartarson's capital finding in ca. 1987 that Greve's Else became the New York dadaist Baroness von Freytag-Loringhoven (FrL), the Spettigue Collections' curator Gaby Divay was able to obtain, in early 1991, FrL's autobiography in typescript and manuscript form from the University of Maryland in exchange for a "Fanny Essler" microfilm.
