Raghab was born on 14 November 1948 at Bhawanipore in Kolkata, one year after India's Independence.

Brought up in north Kolkata, he came in touch with rural Bengal in the late 60s by virtue of his close association with the Naxalite movement.

The publication of Komunis got an encouraging reaction from intellectuals including Ashok Rudra and Malini Bhattacharya.

During this time Raghab also began his career as a professional journalist.

Since his retirement in 2007 he has been heading a publishing house named Charchapada Publication Private Limited.
