Who invented the first water pump?

The first water pump is attributed to the ancient Greek engineer Ctesibius, who lived around 250 BCE. He created a device known as the "syringe pump," which utilized a piston mechanism to draw and expel water. However, various forms of water-lifting devices have been used in different cultures throughout history, including Archimedes' screw in ancient Greece and the shaduf in ancient Egypt. These early innovations laid the groundwork for modern water pump technology.
