Otto von Böhtlingk (May 30, 1815 – April 1, 1904) was a German Indologist and Sanskrit scholar. His magnum opus was a Sanskrit dictionary.
He was born in Saint Petersburg, Russia. 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 1868 he settled at Jena, and in 1885 moved to Leipzig, where he resided until his death.
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 an edition of the Sanskrit grammar of Panini, Aṣṭādhyāyī, 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:
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.
