We all know the word. We hear it just about every day. We see it all the time.
The E in STEM, STEAM, and STREAM stands for engineering.
But do we know what the word actually means? What is engineering? What do engineers do?
Of all the letters in STREAM, I think the E has changed more than all the others, growing, evolving, expanding, adding dimensions and details. I decided to spend some time exploring the meaning of the word engineering, the history of engineering, and just how much the work of engineers influences our day to day lives.
Let’s start at the beginning. What is the simple, basic definition of the word engineer, if there is such a thing?
According to a dictionary from 1967 (1), an engineer is:
1: a man who runs an engine
2: person who plans, builds, or manages engines, machines, roads, bridges, canals, railroads, forts, etc.; expert in engineering
3: member of a group of men who do engineering work in the army or navy
1: v – plan, build, direct, or work as an engineer
2: Amer. – manage cleverly; guide skillfully
Another dictionary (2), a year younger, says this:
1: one versed in or practicing any branch of engineering
2: one who runs or manages an engine; engine-driver
3: a manager; inventor; plotter
4: a member of the division of an army which constructs forts and bridges, clears and builds roads, etc.
Isn’t it nice that in 1968 it was finally recognized that women shouldn’t be excluded from the definition of engineer? But neither of these definitions really seem to fit what I think of when I think of an engineer.
For a more modern definition, I went to the internet.
At Merriam-Webster, I found this definition:
“a person who has scientific training and who designs and builds complicated products, machines, systems, or structures : a person who specializes in a branch of engineering”
That sounds more like what comes to mind when I think about ‘engineer.”
I tried another site, Cambridge Dictionary (4). There I found this definition:
“a person whose job is to design or build machines, engines or electrical equipment, or things such as roads, railways or bridges, using scientific principles”
Besides the issue of gender, I noticed one big difference between the older definitions and the modern ones, – the word ‘scientific.’ Today’s engineers have to know and use scientific laws and principles in their work.
Here’s a video which explains what engineers are and some of the things they do:
Here’s another video, created by the National Science Foundation, in which people share their thoughts about engineering and what they would like to see engineers create in the future.
Humans have always been engineers, but until fairly recently, they weren’t called engineers. Originally the word referred to the designers of military weapons. Later engineers were “locomotive drivers.” As a verb the word could mean less honorable things, such as to connive, trick or deceive. For more information on the history of the word, take a look at the article “The Origin of the Word ‘Engineering,’”
Originally there were just engineers – the people who built catapults, floating bridges, assault towers, roads, buildings, bridges, canals, etc. In the Middle Ages, building engineering advanced with the development of flying buttresses and arches. By the eighteenth century, civil engineering had become a separate, specialized discipline, focused on building structures and designing cities. The Industrial Revolution brought about the creation of mechanical engineering. As scientists learned about electricity, electrical engineering was born. With studies in chemistry chemical engineering was created. And today, as scientists and concerned citizens try to understand global warming, environmental engineering has been born. Hand in hand, science and engineering have developed and grown. As scientists have discovered and learned the laws of the natural world, engineers have found ways to put the new knowledge to practical use. Today engineering has grown to include a multitude of degrees and disciplines.
Generally, there are considered to be 5 major categories of engineering, with a multitude of sub-disciplines within each major field. Here is a list of the major fields of engineering with some of the sub-categories of each:
Civil Engineering: Architectural, Coastal, Construction, Earthquake, Energy, Environment, Forest, Geotechnical, Highway, Hydraulic, Mining, Municipal, Ocean, Railway, River, Sanitary, Solar, Structural, Sustainable, Traffic, Transport, Utility
Chemical Engineering: Biochemical, Biomedical, Biomolecular, Biotechnological, Cellular, Corrosion, Food, Genetic, Materials, Metallurgical, Microbial, Molecular, Paper, Petroleum, Pharmaceutical, Plastics, Polymer, Process, Textile, Tissue, Welding
Mechanical Engineering: Acoustical, Aeronautical, Aerospace, Agricultural, Astronautical, Automotive, Manufacturing, Marine, Mechatronics, Power Plant, Robotics, Sports, Thermal, Wind
Electrical Engineering: Computer, Data, Electronics, Hardware, Information, Mechatronics, Microelectronic, Nanoengineering, Network, Optical, Power, Telecommunications, Web
Industrial Engineering: Apparel, Component, Financial, Fire Protection, Manufacturing, Safety, Supply Chains, Systems
Now we know that the first engineers were not actually called engineers, but do we know who they were? The first person in history to be recognized as an engineer was the Egyptian chancellor Imhotep, who designed and led the building of Djoser’s Step Pyramid at Ṣaqqārah, Egypt. There were countless engineers before him, but their names and achievements have been lost to history. There have been countless engineers since, and many of them have made their marks in history. Others are household names, having influenced the advancement of human society and technology.
According to the site, Interesting Engineering, some of the most famous engineers that we know about are:

So interesting about the gendered language! I’m not surprised, but it’s fascinating to see it remain in writing.
I have a mini-structural engineer in my house, which is really fun. I love seeing how his brain works (very differently than mine). About a year ago we made a video about it: https://www.youtube.com/watch?v=6hCJDQaiQ88&list=PLmDJFibk_1DeiasQzBRhAnQiBB3TObBCI&index=5 and I wrote about it here: https://www.starnetlibraries.org/steam-from-home-side-scooper/
Engineers are problem solvers!
Great video! It looks like y’all had a lot of fun making it. I remember reading your article.
