History of Engineering

The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects.

The term engineering itself has a much more recent etymology, deriving from the word engineer, which itself dates back to 1325, when an engineer ( one who operates an engine) originally referred to “a constructor of military engines. In this context, now obsolete, an “engine” referred to a military machine, a mechanical contraption used in war (for example, a catapult). Notable exceptions of the obsolete usage which have survived to the present day are military engineering corps 

e.g.: the U.S. Army Corps of Engineers.

The word “engine” itself is older origin, ultimately deriving from the Latin ingenium, meaning “innate quality, especially mental power, hence a clever invention.

Later, as the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the older discipline of military engineering.
