  • The IACS and the making of modern Indian science

    Why in the News?

    The Indian Association for the Cultivation of Science (IACS) marked its 150th anniversary this year. It was established on 29 July 1876 as India’s first national institution dedicated to scientific research by Indians.

    What is the Indian Association for the Cultivation of Science (IACS)?

    1. Founding: The IACS was established on 29 July 1876 in Calcutta by Mahendralal Sircar, as the country’s first institution dedicated to scientific research led by Indians.
    2. Founding vision: Sircar proposed the IACS in an 1869 article in the Calcutta Journal of Medicine, arguing that scientific education was indispensable for India’s intellectual and societal progress.
    3. Colonial context: Sircar’s founding was a direct response to what he described in 1872 as the colonial government’s failure to “afford any opportunity” or “encouragement to the pursuit of science by the native of this country.”

    How did the IACS produce Raman’s discovery of the Raman effect?

    1. Raman’s introduction to IACS: After joining the Accountant General’s Office in Calcutta in 1907, C V Raman discovered the IACS and was given open access to its laboratories by Amrit Lal Sircar, the founder’s son.
    2. Dual life as scientist and officer: For nearly a decade, Raman worked at the IACS laboratory in the early mornings and evenings while serving as a government officer during the day, continuing even after he became Palit Professor of Physics at Calcutta University in 1917.
    3. The discovery: Raman made his most celebrated discovery, the Raman effect, in the IACS laboratories, announcing it to the world on 28 February 1928.
    4. Nobel recognition: The discovery earned Raman the Nobel Prize in Physics in 1930, making him the first Asian scientist to win a Nobel Prize in the sciences.

    What does IACS’s history reveal about colonial-era Indian science?

    1. Institutional gap Sircar identified: Sircar’s founding case rested on the argument that Indians needed their own institution because the colonial state had not created one, showing that India’s earliest scientific self-reliance was born out of exclusion rather than official support.
    2. Vision fulfilled: Raman’s Nobel Prize, won through work conducted at an institution founded and funded by Indians, is presented as the fulfilment of Sircar’s original claim that such an institution could produce discoveries of international significance without depending on colonial institutional support.

    Conclusion

    The IACS’s 150-year history runs from Mahendralal Sircar’s 1876 founding, born of colonial neglect of Indian scientific talent, to C V Raman’s 1930 Nobel Prize, won through research conducted entirely within that institution. The anniversary is presented as a reminder that India’s earliest scientific self-reliance predates independence by seven decades.

    Back2Basics:

    1. National Science Day: India observes National Science Day on 28 February each year to mark the anniversary of the announcement of the Raman effect.
    2. Present role: IACS continues to function as an autonomous research institute under the Department of Science and Technology, focused on basic sciences.
