Ctesibius invented a water organ, which was an air pump with valves on the bottom, a tank of water in between them and a row of pipes on top. Another notable invention was a hydraulis, or water organ, in which air was forced through the organ pipes by the weight of water rather than by falling lead weights. While he was an enthusiastic and prolific inventor, he is most famous for two particular inventions. Like many of the significant individuals from antiquity, very little is known about the life of Ctesibius. He recognized that water displaced air in a bucket and used that principle to keep the pressure high in the organ even when the pump was on the recovery cycle.
