Celakovsky, Or Czelakowsky, Frantisek Ladis-Lav, a Bohemian poet and philologist, born at Strakonitz, March 7, 1799, died in Prague, Aug. 5, 1852. He studied at Pisek, Linz, and subsequently at Prague, where he became interested in the Czech language. In 1821 he became instructor in the family of Count Chotck, which left him time for literary pursuits, and he published "Poems" (Prague, 1822; new ed., 1830), "Slavic National Songs" (3 vols., 1822-'7), and a metrical translation of Scott's "Lady of the Lake" (1828). In 1828 he became associate editor of the "Quarterly Review for the Catholic Clergy," and in 1829 published a translation of Russian national songs, which occupies a high place in Bohemian literature. When the Polish insurrection broke out in 1830 he sympathized with Russia; but after the insurrection was suppressed he wrote an article in the "Bohemian Gazette," of which he had become editor, in which he denounced the severity of the Russian government against Poland. In consequence of this article he was deprived of his post as editor of the "Gazette," and also of that of professor of Bohemian literature in the university of Prague, to which he had been appointed.

He then became librarian of Prince and afterward of Princess Kinsky, and in 1842 professor of Slavic languages and literature at the university of Brcslau. In 1848 he returned to Prague, where in the following year, as an act of concession toward the Czech nationality, he was appointed by the Austrian government professor of Slavic philology. One of his latest works was the " Popular Philosophy of the Slavic Nations in their Proverbs" (Prague, 1851). He was engaged from the. year 1835 in a comparative study of all the Slavic dialects, and parts of its results were published in the form of additions to Jung-mann's Czech dictionary.
