Johann Friedrich Böhmer, (born April 22, 1795, Frankfurt am Main [Germany]—died Oct. 22, 1863, Frankfurt am Main), historian known for his Regesta, an annotated collection of charters and imperial documents of medieval Germany.
After studying at the universities of Göttingen and Heidelberg, Böhmer journeyed to Italy, where he became interested in art history. Upon his return to Frankfurt (1822), he became an assistant librarian at the art institute but subsequently devoted himself to general history. Named archivist (1825) and then head librarian (1830) of the city of Frankfurt, Böhmer began publishing the Regesta. The first volume, Urkunden der römischen Könige und Kaiser von Konrad I bis Heinrich VII, 911–1313 (1831; "Documents of the Roman Kings and Emperors from Conrad I to Henry VII, 911–1313"), contained extracts of documents with Böhmer's comments and historical introductions; it was followed by a more extensive treatment for the period 1198–1313. Other Regesta were Urkunden sämtlicher Karolinger (1833; "Documents of the Carolingian Kings") and a series of German imperial registers for the periods 1314–47 (1839), 1246–1313 (1844), and 1198–1254 (1849), with introductions and explanatory passages by Böhmer. He also published Fontes Rerum Germanicarum (1843–68), a valuable collection of original authorities for German history during the 13th and 14th centuries, and he edited many other collections. On his death he left many manuscripts, some of which were subsequently published.
