Eccard, John George

, a German historian and antiquary, was born at Duingen in the duchy of Brunswick, Sept. 7, 1674. Alter studying for some time at Brunswick and Helmstadt, where he made very distinguished progress in the belles lettres and history, he became secretary to the count de Flemming in Poland; and there became acquainted with the celebrated Leibnitz, by whose interest he was appointed professor of history at Helmstadt. After Leibnitz’s death, he was appointed professor at Hanover, where he published some of his works. Although this place was lucrative, he here contracted debts, and his creditors having laid hold of a part of his salary to liquidate some of these, he privately quitted Hanover in 1723, where he left his family, and the following year embraced the religion of popery at Cologne. He then passed some time in the monastery of Corvey in Westphalia; and the Jesuits being very proud of their convert, sent him advantageous offers to settle at Vienna, Passau, or Wurtzbourg. He chose the latter, and was appointed the bishop’s counsel, historiographer, and keeper of the archives and library, and the emperor afterwards granted him letters of nobility. Pope Innocent XIII. seems also to have been delighted with his conversion, although his embarrassed circumstances appear to have been the chief cause of it. He died in the month of February 1730; and whatever may be thought of his religious principles, no doubt can be entertained of his extensive learning and knowledge of history. He wrote, 1. “Historia studii etymologici linguae Germanicas,Hanover, 1711, 8vo. 2. “De usu et pr&stantia studii etymologici linguae Gerjnanicse.” 3. “Corpus historicum medii aevi,” Leipsic, 1723, 2 vols. fol. a work on which the abbe Lenglet | bestows high praise, as very curious and well -digested. 4. “Origines Habsburgo-Austriacae,” Leipsic, 1721, folio. 5. “Leges Francorum et Hipuariorum,” &c. ibid. 1730, fol. 6. “Historia genealogica principumSaxonite superioris, necnon origines Aulialtiiue et Sabaudicae,” ibid. 1722, fol. 7. “Caihechesis theotisca monachi Weissenburgensis, interpretatione illustrate.” 8. “Leibnitzii collectanea etymologica.” 9. “Brevis ad historian!
