Hero (or Heron) of Alexandria (Greek: Ήρων ο Αλεξανδρεύς) (c. 10 – 70 AD) was a mathematician and engineer who was active in Alexandria, Roman Egypt. He is considered the greatest experimenter of antiquity[1] and his work is representative of the hellenistic scientific tradition.[2]
Among his most famous inventions were the first documented steam-powered device, the aeolipile, and a windwheel, constituting one of the earliest instances of wind harnessing.[3][4] He is said to have been a follower of the Atomists. Some of his ideas were derived from the works of Ctesibius.
