Heron (Hero)
When Heron lived is not well established. Most accounts place his life around 0 AD.
Heron, (also known as Hero) was a Greek mathematician. Some authorities place his birthday early BCE in Ptolemaic, Egypt. While other scholars have dated his birth to be CE in late Roman Empire. Nothing is really known of Hero's life, but what we do know comes from clues in the 14 known books by him.
As a student, Hero spent most of his time in the Library at the University of Alexandria. He loved to be in the library, because of the series of gardens vast collection of books. Hero was strongly influenced by the writings of Ctesibius of Alexandria. He may have been a student of Ctesibius. When older he taught at the University of Alexandria, and taught mathematics, mechanics, and physical science. He wrote many books and he used them as texts for his students, and manuals for technicians, and were written in Greek, Latin and Egyptian.

Hero of Alexandria
1st century AD Hellenistic mathematician and engineer
Hero of Alexandria (; Ancient Greek: Ἥρων[a]ὁ Ἀλεξανδρεύς, Hērōn hò Alexandreús, also known as Heron of Alexandria; probably 1st or 2nd century AD) was a Greek mathematician and engineer who was active in Alexandria in Egypt during the Roman era. He has been described as the greatest experimentalist of antiquity and a representative of the Hellenistic scientific tradition.[1][2]
Hero published a well-recognized description of a steam-powered device called an aeolipile, also known as "Hero's engine". Among his most famous inventions was a windwheel, constituting the earliest instance of wind harnessing on land.[3][4] In his work Mechanics, he described pantographs.[5] Some of his ideas were derived from the works of Ctesibius.
In mathematics, he wrote a commentary on Euclid's Elements and a work on applied geometry known as the Metrica. He is mostly remembered for Heron's formula; a way to calculate the area of a triangle using only the lengths of its sides.[6]
Much of Hero's original writings and designs have been lost, but some of his works were preserved in manuscripts from the Byzantine Empire and, to a lesser e
