Giovanni Aldini, Italian physicist and academic (d. 1834)
Giovanni Aldini (10 April 1762 – 17 January 1834) was an Italian physician and physicist born in Bologna. He was a brother of the statesman Count Antonio Aldini (1756–1826).

He became professor of physics at Bologna in 1798, in succession to his uncle Luigi Galvani (1737–1798). His scientific work was chiefly concerned with galvanism, anatomy and its medical applications, with the construction and illumination of lighthouses, and with experiments for preserving human life and material objects from destruction by fire. He wrote in French and English in addition to his native Italian, and in Latin, still used in the 18th century by the scientific community. In recognition of his merits, the emperor of Austria made him a knight of the Iron Crown and a councillor of state at Milan, where he died. He bequeathed a considerable sum to found a school of natural science for artisans at Bologna.
