Source (Wikipedia): Jawaharlal Nehru

Jawaharlal Nehru was an Indian anti-colonial nationalist, secular humanist, social democrat, author and statesman who was a central figure in India during the middle of the 20th century. Nehru was second only to Mahatma Gandhi in leading the Indian nationalist movement in the 1930s and 1940s. Upon India’s independence from Britain in 1947, he served as the country’s first prime minister for 16 years. Nehru championed parliamentary democracy, secularism, science and technology during the 1950s, influencing India’s arc as a modern nation. In international affairs, he is well-known as one of the Founders of the Non-aligned Movement and, concomitantly, for steering India clear of the two blocs of the Cold War. A coveted author, the books he wrote in prison, such as Letters from a Father to His Daughter (1929), An Autobiography (1936) and The Discovery of India (1946), have been read and deliberated upon around the world.
