Indian Science Congress Association (ISCA) is a premier scientific organisation of India with headquarters at Kolkata, West Bengal. The association started in the year 1914 in Kolkata and it meets annually in the first week of January. It has a membership of more than 30,000 scientists.
The Indian Science Congress Association (ISCA) owes its origin to the foresight and initiative of two British chemists, namely, Professor J. L. Simonsen and Professor P. S. MacMahon. It occurred to them that scientific research in India might be stimulated if an annual meeting of research workers somewhat on the lines of the British Association for the Advancement of Science could be arranged.
The Association was formed with the following objectives :
The first meeting of the congress was held from 15–17 January 1914 at the premises of the Asiatic Society, Calcutta. Honorable justice Sir Ashutosh Mukherjee, the then Vice Chancellor of the University of Calcutta presided over the Congress. One hundred and five scientists from different parts of India and abroad attended it. Altogether 35 papers under 6 different sections, namely Botany, Chemistry, Ethnography, Geology, Physics and Zoology were presented.
The Silver Jubilee Session of the Science Congress was held at Calcutta in 1938 under the presidency of Lord Rutherford of Nelson but due to his sudden death, Sir James Hopwood Jeans took the chair. It was at this Jubilee Session that the participation of foreign scientists in session of the Indian Science Congress was first initiated.
