It was fortunate for Zunz that, while at the university, he still kept up his previous studies in Hebrew and Rabbinical lore, for owing no doubt to the knowledge he possessed of these subjects he was appointed, in 1820, the first German preacher of the Reformed Synagogue at Berlin. This appointment, however, he gave up voluntarily, after having held it for two years; the reason for so doing is stated in the preface to his _Collection of Sermons_, which he published at Berlin in 1823. It appears that Zunz, noticing the general indifference of his congregation in religious matters, spoke his mind pretty freely about it in the pulpit. His audiences consequently diminished, and his position became intolerable. He therefore resigned his office, but was lucky enough after to find employment on the above-mentioned paper, which enabled him to marry the lady of his choice. This was Adelaide, _née_ Berman, a relation of David Frankel, Chief Rabbi of Berlin^[142-1]. In 1835 Zunz accepted the offer made by a section of the Jewish community of Prague to become its preacher, but, after a year's stay at Prague, he returned to Berlin, where he was subsequently appointed Principal of the Training College for Jewish teachers. When, in 1850, this institution ceased to exist, Zunz retired into private life, receiving, however, a small pension from the Berlin community as an acknowledgment of the useful services he had rendered to Judaism by his contributions to Jewish science and literature. On this scanty income, sometimes slightly increased by the profits of his books, Zunz and his wife managed to live pretty comfortably, and even occasionally to entertain their friends. Among the latter may specially be mentioned Professor Gans, M. Jost, Joseph Lehmann, M. Moser, Dr. Carrière, the Deputy Warburg, and last, but not least, Heinrich Heine. Heine seems to have been especially attached to them. He used to read to them his poems in MS., some of them, which bear a specific Jewish colouring, were very probably suggested by his learned host^[142-2]. In his visits to England, France, and Italy, Zunz inspected many rare MSS., which had been hidden away in various public and private libraries, and likewise obtained fresh material for his literary works.
