In 1906 Mining Engineering as a discipline was first started in India in this college to meet the requirements of statutory provision in Indian mines. After independence, Dr. B. C. Roy, the then Chief Minister of West Bengal, revamped the department to satisfy the demand for mining professionals, and the Department of Mining & Geology was reborn in 1956. On 12 February 1920 the name was changed to Bengal Engineering College, Shibpur. The word Shibpur was deleted on 24 March 1921 and it became Bengal Engineering College. The Department of Electrical Engineering came into existence as a separate department from 1912. The B.E. degree course was introduced during 1935–36 with the first batch obtaining the degree from Calcutta University in 1936.The inception of the Mechanical Engineering Department may be traced back to 1921 when a diploma course in Mechanical Engineering was started in this Institute. The first degree course in Mechanical Engineering started in July 1930. The Department of Metallurgy started its journey at the Bengal Engineering College in the year 1939 with the introduction of a three-year degree course in Metallurgy under the Calcutta University. The department is the second oldest metallurgy department of the country.
