Hero of Alexandria was an ancient engineer & mathematician who was born in 10 AD and lived in the city of Alexandria, Roman Egypt. Hero developed many inventions with his most famous examples including: Hero's Engine o This is the first known steam engine design and the engineering drawings were developed almost two millenia before the industrial revolution. The steam engine was known as the aeolipile. A later version of the design took the nickname of Hero's engine. The Fire Engine The Wind Wheel o Hero developed many novel designs for music and theatre, but this device is the first known invention to harness windpower. Wind power propelled the wheel padels (to the right of the diagram), which activated a pump that played the organ (to the left of the diagram). Many of Hero's manuscripts and designs have been lost over time, but some were preserved in Arab manuscripts. What manuscripts remain were incorporated into a five volume series of designs in 1903.
