Synopsis The present collection of essays on ‘Dr. Mahendralal Sircar and the National Movement’ is a part of our project on ‘Science and Nationalism in Bengal 1876-1947’ funded by the Indian National Science Academy (INSA). These are seminar papers presented at various local and national seminars from time to time. Each essay is complete in itself. There are biographies of Dr. Mahendralal Sircar by Sarat Chandra Ghosh in English and Samarendra Nath Sen in Bengali but there was no thematic and analytical assessment of Mahendralal in print. This book should fill this gap.
