back to list Heron of Alexandria and His Motor Q: Do you have any info. about "Hero's Motor"? I'm doing a science fair project on the "Hero's Fountain" and I would also like some information about "Hero" and some of his inventions. Thanks. Braydon (age 14) Lockerby Composite Sudbury A: Braydon - Although he's often called Hero, his actual name was Heron. He lived in Alexandria, Egypt in the first century A.D. (From around 10 A.D. to around 75 A.D., probably.) He was a mathematician and inventor, and he focused on geometry and things that had to do with water and air pressure. He's most famous for Heron's Formula, which has to do with the lengths of the sides of triangles. He wrote a lot of books about his work, many of which were stored in the Library of Alexandria. This library is pretty famous because it was lost, so to speak, during wars in that area, and the books inside weren't found until nearly a thousand years later. He came up with a lot of inventions, including what he called the aeolipile, which was the first ever steam-based motor. It was basically a metal ball that could turn on a metal tube that ran through it. It had two bent pipes sticking out opposite sides. Steam came in through the tube in the middle and went out through the pipes on the sides. The steam pushing out through the holes in the sides made the ball spin. Unfortunately, no one ever really used this motor. For more information about Hero's Fountains, check out our answer to the question about that. You can get to it under the Cool Stuff About Air: Water section of our questions list.

AD 60) ranks among the most important scientists of the ancient Roman world in the tradition of Aristotelian experimentation. Heron, about whose personal life virtually nothing is known, resided in Alexandria, Egypt, among the scientists and men of letters of the late Ptolemaic and Roman eras who dwelled around the famed library and museum. A brilliant theoretical scientist and a prolific writer, Heron wrote with clarity and insight. The knowledge of his writings and scientific investigations was preserved in the writings of the late Roman, Byzantine, and Arabic scientists and encyclopedists.

He is believed to have lived in Alexandria; although he wrote in Greek, his origin is uncertain. Several of his works survive either in Greek or in Latin translation. He wrote on the measurement of geometric figures, and a formula for finding the area of a triangle has been ascribed to him. Known for his study of mechanics and pneumatics, he invented many contrivances operated by water, steam, or compressed air; these include a fountain, a fire engine, siphons, and an engine in which the recoil of steam revolves a ball or a wheel.

His works survived because of a wealth of practical information on wine presses, cranes, pulleys, and the like.

Even his name is not definite; he has been called Heron and Hero. No one knows exactly when he lived, though it is commonly believed that he lived sometime between 150 B.C. and 250 A.D. Heron did live in the great scholarly city of Alexandria, Egypt, where many Greek mathematicians and scientists studied. Yet it is not known whether he was a Greek or actually an Egyptian with Greek training. What is sure, though, is that Heron of Alexandria was a brilliant man who gave the modern world much insight into the mathematical and physical sciences. Heron wrote so many works on mathematical and physical subjects that "it is customary to described him as an encyclopedic writer in these fields" (Eves, p. 178). Most of these works can be divided into two categories: geometric and mechanical. While approximately fourteen of his treatises have been uncovered, there are references to other lost works.

Heron von Alexandrien Hero von Alexandrien, Heron aus Alexandrien, Hero aus Alexandrien, Heron Alexandrinus, Heronis Alexandrini Heron of Alexandria, Hero of Alexandria, Heron from Alexandria, Hero from Alexandria Unter allen "alten" Findern und Erfindern ist der Grieche Heron von Alexandrien als außerordentlich bemerkenswert hervorzuheben. Er war ein gelehrter Wissenschaftler, Mathematiker, Mechaniker, Physiker, Naturforscher, Techniker, Ingenieur der Antike und lebte in Alexandrien, Ägypten. Von wann bis wann er genau lebte ist unklar, ein Gelehrtenstreit, aber es war wohl in der Zeitspanne 150 v. Chr. - 250 n. Chr. De Automatis Griech.: Automat = Selbstbeweger Eine Sammlung von Konstruktionen von 'Thaumata', "Wunder"-erzeugenden Geräten speziell für Tempel. Heron beschreibt u. a.: sich selbst entzündende Opferfeuer, drehende und bewegende und tanzende Figuren, Bühnenblitze, Bühnendonner, selbsttätig öffnende und schließende Türen, automatische Musik auf Zimbeln und Trommeln, den Ausfluss von Wein oder Milch aus dem Becher einer Figur. Automaten gibt es mindestens seit dem 3. Jh. v. Chr. Der griechische Mechaniker Philon von Byzanz beschreibt in seiner "Mechanike syntaxis" pneumatische Apparate. Damals gab es sogar automatische astronomische Anzeigegeräte.
