Born on 5th December, 1913 Shri D. B. alias Mamasaheb Kulkarni was a disciple of Late SANE GURUJI under whose tutelage he had imbibed the knowledge and inspiration for Social Work. Shri Kulkarni had worked in our National Freedom Movement at Amalner, Dist. Jalgaon, Maharashtra (during 1938 to 1947) during the emergency period declared by the British Government with SANE GURUJI. During this period Sane Guruji stayed with him when he was underground in disguise. Both came to Mumbai after the independence and worked together till Sane Guruji breathed his last.
