A substantial collection of autograph documents by mainly German, French, and British orientalists, assembled by Alfred Stumpff (1928-2008), a German administrative judge and member of the German-Indian Society of Mainz. There are 133 individual "units", each mostly containing letters but also other documents (such as manuscripts, postcards, and occasional photographs), comprising a total of over 300 pages. The documents date from the 18th through to the 21st century but are predominantly 19th-century.

Among the scholars represented are Silvestre de Sacy (1758-1838), Anquetil-Duperron (1731-1805), the founder of Persian studies in Europe, Antoine-Léonard de Chézy (1773-1832), the editor of Layla and Majnun, Johann David Michaelis (1717-91, discussing Abulfeda manuscripts), Heinrich Leberecht Fleischer (1801-88), Joseph von Hammer-Purgstall (1774-1856), Karl Richard Lepsius (1810-84), pioneer of Egyptology, Georg Friedrich Grotefend (1775-1853), decipherer of cuneiform, Gottfried Kosegarten (1792-1860), and Friedrich Wilken (1777-1840).

Although the bulk of the collection focuses on university-based academic scholarship, several Middle Eastern travelers are included here as well, including Isabella Bird (1831-1904), the first woman FRGS, the physician Michael Erdl (1815-48) and his colleague Johann Martin Honigberger (1795-1869, about his journeys), Jacob Hafner (1754-1809), Claudius James Rich (1787-1820, writing from Baghdad), the naturalist Pierre Sonnerat (1749-1814), and the linguists Théodore Pavie (1811-96) and Eduard Sachau (1845-1930).

Numerous early documents, often from or relating to French and British India, bear witness to the trade maintained between East and West over many centuries.

The folders also include research notes and transcriptions, presumably by Alfred Stumpff.
