Bruno Franz Leopold Liebermann (b. at Molsheim in Alsace, 12 October 1759; d. at Strasbourg, 11 November 1844) was a German Catholic theologian. Life Having finished his humanities in the college at Molsheim, he studied theology from 1776 to 1780 in the seminary at Strasburg, after which, as he was too young for ordination, he was as subdeacon appointed teacher in the college at Molsheim. He became a deacon and a licentiate of theology in 1782, and was ordained priest on 14 June 1783. He shortly afterwards became professor in the Strasburg seminary, in 1784 preacher at Strasburg Cathedral, and in 1787 pastor at Ernolsheim near Molsheim. During the French Revolution he was obliged to take refuge across the Rhine (1792), and the Bishop of Strasburg, Cardinal Rohan, appointed him rector of the seminary which had been transferred for the time to the All Saints' Abbey, in the Black Forest. Here he taught dogmatic theology and canon law, and wrote his unpublished "Institutiones iuris canonici universalis." In 1795 he secretly returned to his parish at Ernolsheim, where he laboured in secret and in great danger for the cure of souls until 1801, holding at the same time the office of extraordinary episcopal commissary for this division of the diocese. In 1801 he was called to Strasburg as preacher at the cathedral and secretary of the diocese, but returned once more to Ernolsheim in 1802. On 12 March 1804 he was there unexpectedly arrested, and, on the groundless suspicion that he was in secret communication with the royal family, was held a prisoner in Paris for eight months. When, through the intercession of Bishop Colmar of Mainz with Napoleon, he regained his freedom, he was called by this bishop to Mainz in 1805 as rector of the newly founded seminary there and in 1806 became also a member of the cathedral chapter. In the seminary he lectured on canon law, church history, pastoral theology, and, after 1812, also on dogmatic theology. Personally and through the clergy trained by him, Liebermann exerted influence in Mainz and the adjoining dioceses. Among his pupils were the future bishops Andreas Räss, Nicolaus von Weis, Johannes von Geissel, and such other distinguished men as Klee, Lüft, Adam Franz Lennig, Franz Xaver Remling, and Nickel. After he had declined in 1823 the appointment to the See of Metz, Bishop Tharin summoned him as his vicar-general to Strasburg.
