- Most Famous For Inventing: Pipe Organ, Hand-Held Crossbow
Working as a mathematician in the Greek city of Alexandria in Ptolemaic Egypt, Ctesibius became one of the world’s greatest inventors. He invented the science behind compressed air and its use in pumps, which is what made cannons work. This was on top of his work on the elasticity of air. He was also responsible for pneumatics, resulting in his “Father of Pneumatics” nickname.
Sadly for Ctestibius, a lot of his work was lost, including ALL of his research. Yet some of his designs remain. Today, we might credit with far more inventions than he has now. However, military types and weapons makers eventually would implement his original design for the hand-held crossbow. He’s also responsible for inventing the pipe organ and the water clock.
