Heron of Alexandria, an incredible inventor from 2000 years ago ~
A wind powered organ! And steam power! And a vending machine! And lots of math calculations, like calculating cube roots. Keep in mind that he lived from 10 - 70 AD
The Dioptra became a mainstay of surveying. He made a type of syringe. And automatons.
Another one who doesnβt receive enough recognition.
