Giovanni Battista Venturi (11 September 1746 – 10 September 1822) was an Italianphysicist, savant, man of letters, diplomat and historian of science. He was the discoverer of the Venturi effect, which was described in 1797 in his Recherches Experimentales sur le Principe de la Communication Laterale du Mouvement dans les Fluides appliqué a l'Explication de Differens Phenomènes Hydrauliques,[1] translated into English by William Nicholson as "Experimental Inquiries Concerning the Principle of the Lateral Communication of a Motion in Fluids," and published in 1836 in Thomas Tredgold's Tracts on Hydraulics.[2][3] Because of this discovery, he is the eponym for the Venturi tube, the Venturi flow meter and the Venturi pump.
