Ishwar Chandra Vidyasagar CIE (Bengali: ঈশ্বরচন্দ্র বিদ্যাসাগর Ishshor Chôndro Biddashagor 26 September 1820 – 29 July 1891), born Ishwar Chandra Bandopadhyay (Bengali: ঈশ্বরচন্দ্র বন্দ্যোপাধ্যায়, Ishshor Chôndro Bôndopaddhae), was an Indian Bengali polymath and a key figure of the Bengal Renaissance. Vidyasagar was a philosopher, academic, educator, writer, translator, printer, publisher, entrepreneur, reformer, and philanthropist. His efforts to simplify and modernize Bengali prose were significant. He also rationalized and simplified the Bengali alphabet and type, which had remained unchanged since Charles Wilkins and Panchanan Karmakar had cut the first (wooden) Bengali type in 1780. He received the title "Vidyasagar" ("Ocean of learning" or "Ocean of knowledge") from the Calcutta Sanskrit College (where he graduated), due to his excellent performance in Sanskrit studies and philosophy. In Sanskrit, Vidya means knowledge or learning and Sagar means ocean or sea. This title was mainly given for his vast knowledge in all subjects which was compared to the vastness of the ocean.
