Ancient Greek mathematician and engineer who was active in his native city of Alexandria, Roman Egypt.
Hero (or Heron) of Alexandria (Greek: Ἥρων ὁ Ἀλεξανδρεύς) (c. 10–70 AD) was considered the greatest experimenter of antiquity and his work is representative of the Hellenistic scientific tradition. Hero published a well recognized description of a steam-powered device called an aeolipile (hence sometimes called a "Hero engine"). Among his most famous inventions was a windwheel, constituting the earliest instance of wind harnessing on land. The first vending machine was also one of his constructions, when a coin was introduced via a slot on the top of the machine, a set amount of holy water was dispensed. Hero also invented many mechanisms like the force pump (for fire-engine), a syringe to control the delivery of air or liquids, a standalone fountain that operates under self-contained hydrostatic energy. (Heron's fountain), a programmable cart that was powered by a falling weight. The "program" consisted of strings wrapped around the drive axle and for the Greek theater, an entirely mechanical play almost ten minutes in length, powered by a binary-like system of ropes, knots, and simple machines operated by a rotating cylindrical cogwheel. The sound of thunder was produced by the mechanically-timed dropping of metal balls onto a hidden drum.
