The Delhi School of Economics is one of India's premier institutes of higher learning. The school was launched in 1949 by V.K.R.V. Rao, with the support of Prime Minister Jawaharlal Nehru. It grew out of a vision that a newly independent nation, which aspired to social and economic progress, needed a vibrant centre for advanced studies in the social sciences. The department of economics, along with its sister departments of geography and sociology, has produced many of the country's leading academics, educators, administrators, policy makers, corporate leaders and journalists. Nobel Laureate Amartya Sen, Prime Minister Manmohan Singh, and the late Sukhamoy Chakravarty, one of the architects of India?s Five Year Plans, have all taught here.
