Educated at the universities of Heidelberg and Göttingen, he showed an interest in art and visited Italy; but returning to Frankfurt he turned his attention to the study of history, and became secretary of the Gesellschaft für ältere deutsche Geschichtskunde.
[2] Böhmer had a great dislike of Prussia and the Protestant faith, and a corresponding affection for Austria and the Roman Catholic Church, to which, however, he did not belong.
[3] Böhmer's historical work was chiefly concerned with collecting and tabulating charters and other imperial documents of the Middle Ages.
[1] Very valuable also is the Fontes rerum Germanicarum (Stuttgart, 1843–1868), a collection of original authorities for German history during the 13th and 14th centuries.
Other collections edited by Böhmer are: Die Reichsgesetze 900-1400 (Frankfurt, 1832); Wittelsbachische Regesten von der Erwerbung des Herzogtums Bayern 1180 bis zu dessen erster Wiedervereinigung 1340 (Stuttgart, 1854); and Codex diplomaticus Moeno-Francofurtanus.
