Answer: Akshay Kumar Dutta
Notes: The Tattvabodhini Pathshala was established in Calcutta on 13 June 1840, and Akshay Kumar Dutta was appointed as one of its teachers. He used to teach geography and physics. As Bangla books on these two subjects were not available at that time he wrote two textbooks Bhugol (1841) and Padarthavidya (1857). His Bhugol is the first science-related book written in Bangla, and through this book Akshay Kumar introduced punctuation marks in the Bangla language.
