Ehsan Danish was born in Maulanan, Kandhla, a small town in the Shamli district of Uttar Pradesh, India.

Later he migrated to Lahore and settled there permanently. He struggled very hard to earn his living. He worked as an ordinary labourer for years in odd jobs, finally becoming a poet of excellence. His autobiography, Jahan-e-Danish, is a classic and has inspired many people. Danish has written more than 80 books and hundreds of articles about and including poetry, prose, linguistics, philology, autobiographies and a famous interpretation of ‘Diwan-e-Ghalib’.
