Archimedes (287-212 BC)
Lived in Syracuse on Sicily. Forever to be known for the Archimedean principle: "a body plunged in a fluid loses as much weight as ..."
Archimedes invented the water screw, a device for raising water using an encased screw open at both ends. The screw is set at an angle, and as the screw turns, water fills the air pockets and is transported upwards. The Archimedes screw is still in use today.
He was the first to describe the lever (around 260 BC). Levers are one of the basic tools; they were probably used in prehistoric times.
