The Tattwabodhinī Sabhā (lit. 'Truth Propagating'/'Searching Society') was a group founded in Calcutta on 6 October 1839 as a splinter group of the Brahmo Samaj, reformers of Hinduism and Indian Society. The founding member was Debendranath Tagore, previously of the Brahmo Samaj, eldest son of influential entrepreneur Dwarkanath Tagore, and eventually father to renowned polymath Rabindranath Tagore. In 1859, the Tattwabodhinī Sabhā were dissolved back into the Brāhmo Samāj by Debendranath Tagore.
