Haller, Johannes

HALLER, JOHANNES. - Protestant historian, b. 16 Oct. 1865 at Keinis (Estonia), d. 17 Jan. 1948 at Tübingen. After completing his university studies at Dorpat, Berlin and Heidelberg, he was in Rome from 1892 to 1897, at the Prussian Historical Institute. Professor of auxiliary sciences of history at Marburg (1902-1904), he subsequently went on to teach history at Giessen (until 1913) and at Tübingen.

A profound connoisseur of the history of the Middle Ages and of the modern age, he acquired renown with the publication of sources on the Council of Basel (Concilium basilense, Studien und Quellen zur Geschichte des Konzils von Basel, 5 vols., Basel 1896-1904). His fundamental work, however, is the history of the papacy as idea and reality through the centuries, which extends down to the times of Innocent III (Das Papsttum. Idee und Wirklichkeit), of which vol. I appeared at Stuttgart in 1934, followed by the two parts of vol. II in 1938 and 1939. Author of valuable syntheses (Die Epochen der deutschen Geschichte, Stuttgart 1923; Tausend Jahre deutsch-französische Beziehungen, ibid. 1930), among his last studies are remembered: Piero da Monte, ein Gelehrter und päpstlicher Beamter des 15. Jahrhunderts (Rome 1941), and Pseudofidors erstes Auftreten im deutschen

Investiturstreit (in Studi gregoriani, II, Rome 1947, pp. 91-101).
