History
On June 14, 1889, Ashwini Kumar Dutta founded Brojo Mohan College, which was named after his father, Brajamohan Dutta.
The first principal of the college was Babu Gyan Chandra Chowdhury. While Ashwini Kumar Dutta taught English and logic, Kali Prasanna Ghosh taught history and Kamini Kumar Bidya Ratna taught Sanskrit and Bengali. In 1898, BM College was transformed into a "First Grade College" from a "Second Grade College". In 1912, the college went to government management from personal management strategy. In the beginning the college used the BM School campus and was relocated its own present complex sometime later.
BM College, affiliated to University of Calcutta, started honours course in English and philosophy in 1922, in Sanskrit and mathematics in 1925, in chemistry in 1928, and in economics in 1929. The time from 1922 to 1948 is called the "Golden Period" of the college. The governor of Bengal at that time, Sir Udbarn, once commented on BM College, "The college promises some day to challenge the supremacy of the metropolitan (Presidency) College."
After the partition of India creation of Pakistan in 1947, the college lacked teachers and the student body fell to one third of its post-war size. This made it difficult to teach the same numbers of courses and as a result the two year Honors curriculum conducted by Calcutta University was replaced with the three Honors curriculum of Dhaka University. As a consequence, Honors courses except Mathematics were abolished in 1950. In 1952, Honors in mathematics had also been discontinued. In 1964, Honors in economics restarted. Several other Honors and Masters Courses started between 1972 and 2005.
The time since 1965 has been called the "Age of Enrichment" of the college. There are 20 degree (pass) courses, 22 Honors courses and 22 Masters courses at BM College.Most recently, on 10 January 2014, the Department of Statistics introduced the Honours Program with only 11 students under the initiative of its founding Head, Professor Biplab Kumar Bhattacharjee, with the support of Professor Nasim Haider. Later, with the assistance of Professor Humayun Kabir of the Department of Sociology, the Master's Program was launched on 18 February 2026. Professor Biplab Kumar Bhattacharjee, under the leadership of Principal Professor S. M. Imanul Hakim, played a key role in reopening the Science Group at the Higher Secondary level in 2016.
