History of the steam engine

The first recorded rudimentary steam engine was the aeolipile, mentioned by Vitruvius between 30 and 15 BCE and described by Heron of Alexandria in 1st-century Roman Egypt. Several steam-powered devices were later experimented with or proposed, such as Taqi al-Din's steam jack, a steam turbine in 16th-century Ottoman Egypt, Denis Papin's working model of the steam digester in 1679 and Thomas Savery's steam pump in 1698.
