Levers have existed since prehistoric times. There is no record of who invented levers. The earliest mention of levers of which there is a record was by Archimedes, but they were in use long before his time.

Archimedes is the Greek scientist who discovered the principle of the lever and invented the double pulley. He did not invent the catapult but he did improve it. He also discovered the when an object is place in fluid, the volume of the fluid that is displaced is equal to the volume of the object.
A foot lever is a lever that is operated with the foot.
The function of a lever is used to move or lift objects.
A fulcrum is a point at which the lever is supported or about which the lever turns.
