The Reverend I. B. Pranaitis (1861-1917) was a Lithuanian Catholic priest, Russian Master of Theology and Professor of the Hebrew Language at the Imperial Ecclesiastical Academy of the Roman Catholic Church in Saint Petersburg, Russia. In 1894 there were legal proceedings against him on a charge of blackmail (for demanding 1000 roubles from a framing workshop in indemnification for a spoilt cheap picture which he claimed to be a picture by Murillo). For some time he was banished to Tver. [3]Since 1902, he was a priest in Tashkent. He published an anti-Semitic tract called Christianus in Talmude Iudaeorum in Latin in 1892 under the imprimatur of the Archbishop Metropolitan of Mogilev, which was subsequently translated into Polish, French, German, Russian, Lithuanian, Italian, English and Spanish. The English translation of the book is titled The Talmud Unmasked: The Secret Rabbinical Teachings concerning Christians.
