Excerpt from Transactions of the American Society of Heating and Ventilating Engineers, Vol. 8: Eighth Annual Meeting, New York, January 21-23, 1902, Summer Meeting, Atlantic City, N. J., June 16, 1902 During the first half of the nineteenth century, engineers were classed under two heads: military engineers and civil engineers. The military engineers were those who did work of an engineering character in connection with military opera tions. They built forts, military roads, bridges and other structures whose primary use was for military operations, for facilitating offensive and defensive movements. Military engineers were, as a rule, soldiers first and engineers sec ond. Under the head of civil engineers were classed all those men who had to do with engineering work which did not per tain to military operations. All engineering work of what ever character which was civil and not military, was done by the civil engineers. Towards the middle of the nineteenth century, the civil engineering work became so varied and diversified that engi neers other than military engineers were classed under two heads; namely, civil and mechanical engineers. Civil engi neers were those who built structures which were at rest, structures such as bridges, buildings, viaducts, sewage sys tems, water works, etc. Mechanical engineers were those who built machines - objects which were to be for the most part in motion. They built steam engines, machinery for factories, locomotives, steamships, etc. The civil engineer had to do largely with that part of mechanics called statics, while the mechanical engineer had to do largely with that part called dynamics. Later, each of these large branches, civil and mechanical engineering, was subdivided into a number of smaller divisions, and the engineer who did work pertaining to one of the smaller divisions was termed an electrical engi geer, a sanitary engineer, a steam engineer, a bridge engineer, or a structural engineer, depending upon the branch of work in which he was engaged.
