Jozef Karol Hell (Slovak: Jozef Karol Hell, German: Josef/ph Karl Hell, Hungarian: Hell Jozsef Karoly) (15 May 1713, Banska Stiavnica - 11 March 1789, Banska Stiavnica) was a Hungarian mining engineer and inventor, who invented the water-pillar (water pump machine) in 1749 (first use 1753). It is mainly used today for oil extraction. He also proposed construction of the tajchy reservoirs around Banska Stiavnica. He was a student of Samuel Mikoviny in 1737. Regardless of his nationality, he is a pride of both Hungarian and Slovak nations.
His first machine was able to pump water up from the depth of 212 meters. Jozef Karol Hell later built the pumping machines in 1749-1768, which belongs to the best technology in this field worldwide.
