Calcutta Mathematical Society
The Calcutta Mathematical Society (CalMathSoc) is an association of professional mathematicians dedicated to the interests of mathematical research and education in India. The Society has its head office located at Kolkata, India. History

Calcutta Mathematical Society was established on 6 September 1908 under the stewardship of Sir Asutosh Mookerjee, the then Vice-Chancellor of Calcutta University. He was the founder president of the Society, and was assisted by Sir Gurudas Banerjee, Prof. C.E. Cullis and Prof. Gauri Sankar Dey as Vice Presidents and  Prof. Phanindra Lal Ganguly as the Founder Secretary of the organization. It is said that the founders were inspired by the structure and operations of the London Mathematical Society while forming this organization. Over more than the last 100 years, the Society has fostered teaching and research of theoretical and applied mathematical sciences through several pedagogic and technical activities. It is honored to be associated with legends like Albert Einstein, Anil Kumar Gain, S. Chandrasekhar, Abdus Salam and many more eminent scientists and researchers across the globe. Activities

The main academic activities of the Society can broadly be classified under the following three heads: Memorial Lectures, Special Lectures and Regular Seminars and Symposiums. The Memorial Lectures are organized by the Society every year in honor of great academicians who were once associates and patrons of the organization. The Special Lectures are given on request by eminent researchers and scientists who visit Kolkata from time to time. The Seminars and Symposiums are generally held on an annual basis, focusing on the Pedagogic and Technical topics as well as topics of popular interest. 'International Symposium on Mathematical Physics in memory of S. Chandrasekhar with a special session on Abdus Salam' is notable one. National seminars on 'Theory & Methodology of Mathematics Teaching', 'Contribution of René Descartes','Contribution of Gottfried Leibniz', National Seminar on 'Power generation, Environment Pollution and related Mathematical Equations' were the most notable programme. Director of all those programs was Professor N. C. Ghosh. Professor C. G. Chakraborty was Director of National seminar on 'Satyndranath Bose & his contribution', Professor B. N. Mondal was Director of the 'Workshop on Mathematics Teaching Research & Training' organised at Calcutta Mathematical Society.
