The story
Founded by Lewis Leigh Fermor on Jan 7, 1935.1
The origins of INSA can be traced back to the founding of the National Institute of Sciences in India (NISI) in the year 1935 in Calcutta (now Kolkata). The basic objective was, and continues to be, to promote, nurture and safeguard the interests of science and scientists. The NISI was recognised by the Government of India as a Premier National Scientific Society. NISI moved to its present premises in Delhi in 1951. A Government of India decision in 1968 mandated INSA to represent India in all the international science fora. In 1970, NISI was given a new name- Indian National Science Academy (INSA). Its campus at Bahadur Shah Zafar Marg came into being in 1951, with a major expansion during the late 80's-mid 90's. Today the main INSA building stands out at Bahadur Shah Zafar Marg as a seven-storied, beautifully shaped Golden Jubilee Building, completed in 1996.
