Extractions: 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.

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. One of Heron's outstanding treatises was the Metrica

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.

Alexandria, c. 10 ce , d. c. 75] Heron is thought to have taught at the Museum in Alexandria, and the books that are attributed to him were probably based on lecture notes, as with Aristotle's works. Many of his writings are known in Greek or in Arabic or Latin translations, including Automaton Making, Geometrica, Mechanica (for architects), Metrica (on measurement), Catopricis (on mirrors), Pneumatics (on mechanical devices worked by air, steam, or water), Siegecraft, and Dioptra (on the surveyor's transit), as well as a fragment on water clocks and parts of a dictionary of technology. His works survived because of a wealth of practical information on wine presses, cranes, pulleys, and the like. He is best remembered today for a pinwheel that operated by steam, often called the first steam engine. He was also a creative mathematician. Dictionary He·ro hÄ rÅ, h®r

Resources Heron of Alexandria Not much is known about the man named Heron of Alexandria. 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.
