T.S. Ramanujam, born in 1906, began his career as a labour leader in the Railway union loaders' association, dedicating himself to advocating for labour rights and welfare. He expanded his efforts to the northern parts of Chennai, where numerous industrial areas were located, uniting workers and standing up for their rights. In his youth, he formed a close friendship with Sri V.V. Giri, who later became the President of India. Together, they actively participated in protests and movements to secure labour rights. In honour of T.S. Ramanujam's contributions, Sri V.V. Giri laid the foundation stone for the Narbhavi Trust after Ramanujam's passing, ensuring the continuation of his legacy in supporting labour welfare. 

Mathurabai Ketkar, born in 1905 in Pune, was a pioneering woman who defied societal norms by pursuing education abroad, setting a remarkable example for women's empowerment. After marrying T.S. Ramanujam, she stood by him, offering moral support through her education. Together, they envisioned a society where women were independent and self-reliant, challenging traditional gender roles and inspiring many in their community. In 1968, T.S. Ramanujam passed away, after that Mathurabai Ketkar, continued their shared vision by dedicating herself to community service in his memory. Recognizing the importance of supporting labourers, she established the Narbhavi Trust to continue their work. K. Eswaran, the chairman of the Easun Group, a close friend of T.S. Ramanujam, stepped in to support the initiative, ensuring the trust's success and the continuation of their shared mission. Through their combined efforts, Mathurabai Ketkar and K. Eswaran have left a legacy in Chennai, promoting women's empowerment and labour welfare, and inspiring future generations to continue their work.
