The Indian Military Academy (IMA) saw its origin on October 1, 1932, with Brig L P Collins as its first Commandant. The first course, the Pioneers, had on its roll Sam Manekshaw, Smith Dun and Mohd Musa, all of whom later became the Chiefs of the armies of their respective countries (India, Burma and Pakistan). The government acquired the estate of the erstwhile Railway Staff College at Dehra Dun which had fairly extensive campus to meet the needs of the Academy at its birth.

Eventually, the British officers departed and Lt. Col. Thakur Mahadeo Singh, in the enhanced rank of Brigadier, became its first Indian Commandant in free India. In May 1947, the Academy had the privilege of receiving Pandit Jawahar Lal Nehru and Sardar Vallabh Bhai Patel. This historic visit imbued the officers and cadets with patriotic fervour.

During the World War II, the importance of inter-dependence of the three services was realised. The Government of India, therefore, approved the creation of an Inter-Services Wing for training cadets for the Army, Navy and the Air Force together. Thus, in January 1949, the Academy was redesignated as Armed Forces Academy, with the military wing in the present campus and the Inter- Services Wing at Clement Town. The post of the Commandant was upgraded from that of a Brigadier to a Major General.

In consonance with national aspirations, the Indian Military Academy was redesignated as the National Defence Academy in January 1950. The Inter-Services Wing became Joint Services Wing (JSW). The first JSW course passed out in December 1950. In December 1954, the Joint Services Wing moved to Khadakvasla. The Indian Military Academy, renamed as Military College, retrieved its original identity and role. In 1960, the Military College was renamed the Indian Military Academy.

In the year 1956, ONGC has established its Head Quarters in the famous Building, Tel Bhawan(Patiala House), at Dehradun. ONGC is the premier exploration and production company in India and accounts for 90% of the exploration effort, established reserves and production of oil and gas in the country. ONGC have built an organization with fiscal, technical and managerial strength to match any large oil company in the world. It is thus obvious that ONGC would continue to be a major force in the Indian oil industry in the foreseenable future.

KDMIPE a unit of ONGC was first set up in 1962 as a research and training institute with assistance from United Nations Development Programme, it evolved into Institute of Petroleum Exploration in 1974. The Institute was christened as Keshava Deva Malviya Institiute of Petroleum Exploration in the year 1981 in memory of first Minister of Petroleum Shri Keshava Deva Malviya. KDMIPE caters to the research needs of ONGC's operating regions in the field of Geosciences for hydrocarbon exploration/exploitation and development of alternative sources of energy, besides undertaking large number of need based essential and research projects directed at testing new methodologies, technology upgradation, development of new and novel ideas, generation and updating of geoscientific data and computer applications.

Survey Of India, The National Survey and Mapping Organization of the country under the Department of Science & Technology, is the Oldest scientific department of the Government Of India. It was set up in 1767 . Forerunners of army of the East India Company and Surveyors had an onerous task of exploring the unknown. Bit by bit the tapestry of Indian terrain was completed by the painstaking efforts of a distinguished line of Surveyors such as Mr. Lambton and Sir George Everest. It is a tribute to the foresight of such Surveyors that at the time of independence the country inherited a survey network built on scientific principles. The great Trigonometric series spanning the country from North to South East to West are some of the best geodetic control series available in the world. The scientific principles of surveying have since been augmented by the latest technology to meet the multidisciplinary requirement of data from planners and scientists.
