Giovanni Battista Venturi (15 March 1746 - 24 April 1822) was an
Italian physicist, savant, man of letters, diplomat and historian of science. He was the discoverer of
Venturi effect, which was described in 1797 in his
Recherches Experimentales sur le Principe de la Communication Laterale du Mouvement dans les Fluides applique a l'Explication de Differens Phenomenes Hydrauliques, translated into English in 1837 by
Thomas Tredgold as "Experimental Inquiries Concerning the Principle of the Lateral Communication of a Motion in Fluids," in
Tracts on Hyraulics. Because of this discovery, he is the
eponym for the
Venturi tube, the Venturi flow meter and the
Venturi pump.
