Rathindranath was the youngest one in the Tagore family amongst all his cousin brothers and sisters . In a big-book known as "Paribarik Khata" was kept in his uncle's (Satyendranath) house for writing comments by the members of the Tagore family where he was marked as a shy and introvert one by his cousin brothers and sisters. He was born in 1888 and remained in Jorasanko upto the age of 10 yrs and his preliminary education from a Nusrsery trained teacher and his wife. He was then admitted in a school at Silaidah founded by his father. He got his education from his father and three other teachers there.. He took admission as a founder student, among 4 others, in Santiniketan Brahmmacharyasram in 1901 after studying 3 years in Silaidah.. He passed Matriculation examination in 1903 and was trained at home for 3 years to be admitted in Illionos University to study BS in agricultural Science in 1906. He passed BS in agriculture in 1909, had an educational tour to different countries of Europe and had come back home in the same year at the call of his father. He had gone to Silaidah and Patisar to get himself acquainted with the tenants of the estate. He started an agricultural farm with a laboratory for soil taste in Patisar. In 1910 he was married to Pratima and then came to Santiniketan to take some responsibility of his father in the mangement of the Institution. He wanted to stay permanently in the Kuthibadi of Surul but was unable to stay there as they were attacked with malaria and came back to Santiniketan. He permanently stayed in Santiniketan with his wife Pratima unless he was deputed for other responsible job.He got 4 genuine responsibilties; .1. to look after the Zamindary including to conduct village court founded by his father, 2. to look after his farm at patisar, 3.to look after the administration and development of Santiniketan, 4. to accompany his father in his foreign tour. Rathindranath was not only one of the first five boys of the Santiniketan Brahmacharyasrama, he was also one of the key persons for the existence and development of Santiniketan. Rathindranath was one of the most representative product of Rabindranath's educational ideals. After his matriculation, Rathindranath was sent to Illinois to study Agricultural Science. He spent the next four decades of his life serving Santiniketan and Visva-Bharati.
At Santiniketan, he taught genetics to the students and he had been praised for making such a technical subject interesting to the students. Apart from teaching he worked mostly behind-the-scenes, organising, trying to find newer and better methods to implement ideas. At different times he had been the Karma-Sachiva and teacher. As a Santiniketan-Sachiva, in charge of Sriniketan, he served for about fifty years after his joining the Brahmacharyasram. He did a lot to promote it to Visva-Bharati University, a Central University in 1953 and became its first Upacharya.Without his active patronage, the Tagore memorial and archives perhaps could never have come into existence. He made over his heir loom to Visva-Bharati and a part of his income to Rabindra Bharati.
