You've never heard of her, yet until fairly recently, one of her inventions was an unavoidable part of your life: Marget E. Knight is the person who realized a flat-bottomed paper bag would hold a lot more than a flat bag and proceeded to invent a machine to automatically cut, fold and glue them, not too long after the end of the U.S. Civil War.
Who was she, some kind of engineer? --Well, some kind, I suppose, but she'd left school at the age of 12 to work in the textile mills of her native New England; her first invention was a device to improve worker safety on looms, variously described as a "covered shuttle" or "stop-motion device,"* and widely used (yes, by those grasping, greedy capitalists...who didn't like having to stop a machine or an entire mill to untangle a mangled worker, train her replacement, etc.: it turns out that safety saves!). Later on, she went to work in a paper bag factory, where the notion of the flat-bottomed bag occurred to her. --She almost didn't get the patent, when the machinist she hired to build an all-metal Patent Office model from her wooden prototype stole the design instead and tried to patent it himself! In 1871, she won the patent interference claim on the strength of her detailed, dated notes -- which does indeed make her some kind of an engineer in my opinion.
Never wealthy, never a fancy "inventor" with an office and a staff, Margaret E. Knight is nevertheless one of my heroines, a systematic thinker who saw things through.

Just because she didn't have a diploma doesn't make her not an engineer. Dean Ing uses the term "mustang engineer" in one of his stories to describe someone with the knowledge and skills but no sheepskin; works for me.
I work with a few of those "mustang engineers" who only missed a diploma because something got in the way of college. I've learned a lot from them.
With men engineers, spare time and paper folding machines however...
^^^That is why we can't have nice things.
