Ishwar Chandra (Vidyasagar Ishshor ChÃ´ndro Biddashagor 26 September 1820 â€“ 29 July 1890), born Ishwar Chandra Bandopadhyaya (Ishshor ChÃ´ndro BÃ´ndopaddhae), 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 Bangla 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 Bangla type fonts in 1780.
