Jadugopal or Jadu was born at Tamluk in the district of Medinipur on the bank of the Rupnarayan River in West Bengal, where his father Kishorilal practised law and distinguished himself as a Kheyal singer.

Fond of observing and analysing the rising tide of patriotism and the Government measures to repress them, Jadu preferred remaining aloof, confining himself to a couple of close friends.

Busy cementing the regional units for organising an armed insurrection during the forthcoming War, Jatin designated Rash Behari Bose as the responsible for Upper India.

Hiding in the hilly forests of Assam-Burma and Tibeto-Bhutan frontiers, Jadu was informed about the impact of the revolutionaries' activities on the Imperialists and about the question of a possible concession of constitutional reforms with the Rowlatt Act at the end of World War I.

After Gandhi's first failure, according to their initial contract, the Jugantar members worked under Deshbandhu Chittaranjan Das and Satyendra Chandra Mitra to form the alternative Swaraj movement and they declared their new programme by celebrating the 8th anniversary of Bagha Jatin's self-giving on 9 September 1923, from Bengal to Punjab.

After receiving a message from Lala Har Dayal, Pandit Ram Prasad Bismil went to Allahabad where he drafted the constitution of Hindustan Republican Association in the winter season of 1923 with the help of Dr. Jadugopal Mukherjee and Sachindra Nath Sanyal both of these revolutionaries were from Bengal.
