Heron was a teacher and researcher at the Musaeum of Alexandria, the famous library and university in Alexandria. Some of his writings are elaborate textbooks, others are lecture manuscripts in style.
The complete works of Heron represent something like an encyclopedia of applied mathematics and engineering sciences of the Greco-Roman era. His best known mathematical work is the formula for the area of a triangle in terms of the lengths of its sides. One of his most famous inventions was an experiment done as part of the earliest instance of harnessing wind energy on land.
He is said to have philosophies related to atomists, which he discussed in his work Mechanics. He also described pantographs.
Many scholars believe that not only he taught at the Musaeum of Alexandria, but that in addition he served as its Director and that he developed it as the first Polytechnic School, or Technical Institute.
He was made famous for documenting the first steam turbine, the aelolipile. He also invented many mechanisms for temples and theaters while he advanced or improved inventions by others, for example the hydraulis, originally invented by Ktesibius.
His most important invention was the Aeolipile, the first steam turbine. Other inventions include automated machines for temples and theaters, surveying instruments, and military machines and weapons.
