Who are some great Indians that most people have not heard of?
Meet Padma Shri Haldhar Nag

He was born in a poor family in Odisha. He was forced to drop-out from school to support his family after the death of his father.

Haldhar did odd jobs like washing dishes, and cooking at a school for years.

It was during this period that he started writing. His first poem, 'Dhodo Bargachh' (The Old Banyan Tree) was published in a local magazine in 1990.

He is called 'Lok Kabi Ratna' in Odisha and has written on nature, society, mythology and religion other than taking up the cause of the oppressed. A collection of his works titled Haldhar Granthabali-2 will be soon published by Sambalpur University and it will be a part of their syllabus.

His contribution in the academic sector doesn't end there. Five scholars have done their PhD research based on the works of Nag.
