Satyendranath Tagore became the first Indian to join the Indian Civil Services in 1863 after the British government allowed Indians to compete (his brother Rabindranath Tagore was a Nobel laureate writer). Swami Vivekananda was a spiritual leader, Prasanta Chandra Mahalanobis was a statistician (founder of ISI), and Rabindranath was a writer, not a civil servant.
