The water screw, still saving lives of people in rural areas without access to clean water, was invented by which ancient genius inventor?

The Archimedes screw (also called the screw pump) is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. It remains in use today in developing countries for lifting water and is also used in wastewater treatment plants. Archimedes of Syracuse (3rd century BCE) is credited with its invention, though it may have been invented earlier in Egypt. Ts'ai Lun invented paper, Ibn al-Haitham was an optical physicist, and Dostoyevsky was a novelist.
