Johan Olof Wallin

Johan Olaf Wallin was born at Stora Tuna, in 1779, and early displayed his poetical powers. In 1805, and again in 1809, he gained the chief prize for poetry at Upsala. In the latter year he became pastor at Solna; here his ability as a preacher was so striking that he was transferred to Stockholm, in 1815, as "pastor primarius," a title for which we have no exact equivalent. In 1818 he was made Dean of Westeras, and set about the task of editing a revised hymn-book for the whole of Sweden. This task he completed in 1819, and published it as, Den Swensha Psalmboken, of Konungen gillad och stadfdstad (The Swedish hymn-book, approved and confirmed by the King). To it he contributed some 150 hymns of his own, besides translations and recastings; and the book remains now in the form in which he brought it out. It is highly prized by the Swedes, and is in use everywhere.
