Hero of Alexandria Biography
(Greek Mathematician and Engineer)
Born In: Alexandria, Egypt
Hero of Alexandria was a mathematician, engineer, and inventor. Considered as the greatest experimenter of his time, Hero of Alexandria invented the windwheel among many other devices. He published a detailed description of a steam-powered instrument called an ‘aeolipile,’ which is also known as ‘Hero’s engine.’ Some of his ideas were inspired by the works of a Greek inventor and mathematician Ctesibius. Many of Hero’s original designs and writings have been lost. However, some of them are preserved in the form of manuscripts. As a mathematician, he came up with an iterative method for calculating the square root of a number. Also, ‘Heron’s formula,’ which is used to compute the area of a triangle, is named after him.
