Otto von Böhtlingk (, Otton Nikolayevich Byotlingk; 30 May 1815 – 1 April 1904) was a Russian-German Indologist and Sanskrit scholar. His magnum opus was a Sanskrit-German dictionary. Biography He was born in Saint Petersburg, Russia. His German ancestors migrated to Russia from Lübeck in 1713. Having studied (1833–1835) Oriental languages, particularly Arabic, Persian and Sanskrit, at the University of Saint Petersburg, he continued his studies in Germany, first in Berlin and then (1839–1842) in Bonn. Returning to Saint Petersburg in 1842, he was attached to the Royal Academy of Sciences, and was elected an ordinary member of that society in 1855. In 1860 he was made Russian state councillor, and later privy councillor with a title of nobility. In 1862, the American Philosophical Society elected him an international Member. In 1868 he settled at Jena, and in 1885 moved to Leipzig, where he resided until his death. Scholarship Böhtlingk was one of the most distinguished scholars of the nineteenth century, and his works are of pre-eminent value in the field of Indian and comparative philology. His first great work was a translation of the Sanskrit grammar of Panini, , with a German commentary, under the title Acht Bücher grammatischer Regeln (Bonn, 1839–1840). This was in reality a criticism of Franz Bopp's philological methods. This work was followed by: Vopadevas Grammatik (Saint Petersburg, 1847) Über die Sprache der Jakuten (Saint Petersburg, 1851) Indische Sprüche, a series of Sanskrit apothegms and proverbial verses (2nd ed. in 3 parts, Saint Petersburg, 1870–1873, to which an index was published by Blau, Leipzig, 1893) a critical examination and translation of the Chandogya Upanishad (Saint Petersburg, 1889) a translation of the Brihadaranyaka Upanishad (Saint Petersburg, 1889) His magnum opus was his great Sanskrit-German dictionary, Sanskrit-Wörterbuch (7 vols., Saint Petersburg, 1853–1875; shortened ed. (without citations) 7 vols, Saint Petersburg, 1879–1889), which with the assistance of his two friends, Rudolf Roth (d. 1895) and Albrecht Weber (b. 1825), was completed in 23 years. He also published several smaller treatises, notably one on Vedic accent, Über den Accent im Sanskrit (1843). Also notable are his Sanskrit-Chrestomathie (Saint Petersburg, 1845; 2d ed., 1877–97), and an edition with translation of a treatise on Hindu poetics by Daṇḍin, Kāvyādarśa (Leipzig, 1890). Böhtlingk took up Panini's grammar again, 47 years after his first edition, when he republished it with a complete translation under the title Panini's Grammatik mit Übersetzung (Leipzig, 1887). It
