The descriptions match Rettai Malai Srinivasan (also known as R. Srinivasan), a prominent Dalit leader from Tamil Nadu. He was honored with titles like Rao Sahib, Rao Bahadur, and Divan Bahadur by the British government for his public service. His autobiography, "Jeeviya Saritha Surukkam" (A Brief Autobiography), is considered one of the earliest autobiographies in Tamil and by a Dalit leader. He was a key figure in the early Dalit movement and was instrumental in founding the Adi Dravida Mahajana Sabha in 1893, an important organization for the upliftment of Dalits (Adi Dravidars).
