of Alexandria Hero
An inventive mind from ancient Alexandria, this mathematician-engineer is remembered for turning abstract ideas into striking machines, from automata to an early steam-powered device. His surviving works helped preserve a rich mix of geometry, mechanics, and practical problem-solving from the ancient world.

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 known as Heron — is one of the best-known scientific writers of antiquity. Reference works including Encyclopaedia Britannica describe him as a Greek geometer and inventor whose writings preserved important mathematical and engineering knowledge.
He is especially famous for practical, ingenious devices. Accounts of his work highlight the aeolipile, often described as the first known steam-powered device, along with writings on pneumatics, surveying, mechanics, and automation. That mix of theory and hands-on experimentation is a big part of why he still feels surprisingly modern.
For readers today, Hero stands out not just as a mathematician, but as a clear example of how ancient science could be playful, useful, and imaginative at the same time. His name is also linked to Heron’s formula for the area of a triangle, a reminder that his legacy reaches from classroom geometry to the history of invention.
