The pneumatics of Hero of Alexandria
by of Alexandria Hero
About the author
Probably active in the 1st century CE in Alexandria, Hero of Alexandria—also called Heron—was a Greek mathematician and engineer whose surviving works became some of the best-known technical writings of the ancient world.
He wrote on geometry, surveying, mechanics, and pneumatics, and his books describe everything from measuring land to building automata and water-powered devices. Many readers know him for Heron's formula for finding the area of a triangle from its side lengths, while historians of science often point to his Pneumatica and other treatises as vivid examples of hands-on experimentation in antiquity.
Although details of his life are uncertain, his reputation has lasted because his writing preserves a remarkable mix of theory and practical know-how. For modern listeners, Hero offers a window into the inventive spirit of Alexandria, where mathematics and engineering were closely tied to curiosity, craftsmanship, and showmanship.
