Read the following paragraph and extract the answer for the question: What is the first name of the father of the person from the Tagore legacy that is associated with the educational reformer?  Narrated by Satyajit Ray, the film begins with the funeral procession of Rabindranath Tagore. Briefly mentioning about Kolkata, then known as "Calcutta", the documentary explains the Tagore lineage, starting with Dwarkanath Tagore. While documentary mentions Dwarkanath Tagore's elder son Debendranath Tagore's association with an Indian religious, social, and educational reformer Raja Rammohun Roy and introduces some of his children out of fourteen, it moves to the birth of child Rabindranath Tagore, fondly called as "Robi". The film then narrates Robi's initial schooling days, his trip to northern India with his father, publication of his first poem in his father's magazine and his failed attempt for higher education at London. The documentary showcases some of the scenes of Tagore's first drama-opera, Valmiki Pratibha (The Genius of Valmiki), where he used western classical music along with Raga-based songs to narrate sage Valmiki's story and himself acted in the lead role. Mentioning about his marriage with Mrinalini Devi, the documentary explains his aim to form a new school at Santiniketan and its different education system, death of his wife and children in the short span of time and his association in Indian independence movement. It then narrates Tagore's visit to England in 1912 where his English translated poems from Gitanjali were introduced to English painter William Rothenstein, who in-turn showed them to the Irish poet W. B. Yeats. This helped Gitanjali for its publication in England and fetched Tagore the Nobel Prize in Literature in 1913 and a Knighthood in 1915.

Dwarkanath
