You might have come across email with pictures of tajmahal premise and someone called as Prof. Oak claiming it to have been built by an Indian King a long before Mughal era. I just could not stop myself from cluches of curiosity when I read the mail. So, I decided to research myself. And obviously, GOOGLE zindabad. I got to know a lot about this historian whom not many people know, who is actually beleived to be one of the greatest historian humanity had ever had. He contruibuted his lifetime for research on Indian ancient history.
