Who among the following established the Calcutta Unitarian Committee ?

The Calcutta Unitarian Committee was established in 1821 by Raja Ram Mohan Roy in collaboration with William Adam and Dwarkanath Tagore [t5][t6]. William Adam, a Scottish Baptist missionary, was famously converted to Unitarianism by Roy, leading to their joint efforts in promoting monotheistic and reformist ideas [t6][t8]. The committee served as a precursor to the Brahmo Sabha, which Roy later founded in 1828 [t7]. The organization aimed to foster intercultural connections between Hindu reformers and Western Unitarian Christians, focusing on religious and social transformation [t6][t7]. While Keshab Chandra Sen and Ishwar Chandra Vidyasagar were significant figures in the later Brahmo Samaj movement, they were not the founders of the Unitarian Committee; Sen joined the Samaj much later in 1857 [t2][t3]. Therefore, Raja Ram Mohan Roy is the primary figure associated with its establishment [t7].
