History of the Anushilan Samiti
Around 1902, Aurobindo Ghosh arranged for Bannerjee to return to Calcutta to begin organisational work, where he began a gymnasium and a youth society. It was at this time that Bannerjee came in touch with Vibhuti Bhushan Bhattacharya, Sarala Devi Ghoshal and Pramathanath Mitra. In Calcutta, a few clubs and societies were still active at the time. Most notable was a gymnasium in Ballygunge Circular Road run by Sarala Devi herself, a second was an organisation named "Anushilan Samiti" founded by Satish Chandra Basu with the patronage of Pramathanath Mitra. A third one was a youth club called "Attōnnōti Samiti" (Self-improvement society) in central Calcutta.
Atulkrishna Ghosh
According to Nixon’s Report, probably in about 1913, or perhaps a little before, certain of the old members of the Kolkata Anushilan Samiti who, in the meantime, had been members of various athletic clubs, formed themselves into a branch of the "Seva Samiti" under Atulkrishna Ghosh: "The ostensible object of this "samiti" was a benevolent one. The first centre was at the house of Atul Ghosh. During the Burdwan floods, in 1913, many members of this "samiti" went there for the purpose of affording relief to the afflicted people.". Atul’s efficiency and generosity as a leader became evident during this relief.
