Tiberius Cavallo (March 30 1749 - December 21 1809) was an Italian physicist and natural philosopher. In 1771 he went to England with the intention of pursuing a mercantile career, but he soon turned his attention to scientific work. He made several improvements in scientific instruments. He was often cited in the literature of his time as inventor of Cavallo's multiplier, a device he used for the amplification of small electric charges, making them observable and measurable in an electroscope. He also worked on refrigeration, and his work influenced pioneer balloonist Jean-Pierre Blanchard. He published numerous works on different branches of physics including; A Complete Treatise on Electricity (1777), Treatise on Magnetism (1787), and Elements of Natural and Experimental Philosophy (1803). He died in 1809 at the age of 60.
