Giovanni Aldini

Born in Bologna in 1762, Giovanni Aldini was the nephew of Luigi Galvani and became one of the leading promoters of galvanism, the study of electricity in living bodies. He taught and wrote about the subject at a time when electricity was still mysterious, and he worked hard to spread these ideas beyond Italy.

Aldini is especially remembered for his public experiments showing how electrical currents could make muscles contract. In London, he famously used electricity on the body of an executed criminal, a demonstration that captured the public imagination and helped make his name widely known. He also carried out experiments on animals and developed electrical devices, linking scientific research with practical invention.

He died in 1834, but his reputation has lasted because his work sits at the crossroads of science, medicine, and spectacle. For modern readers, Aldini remains a fascinating example of how early electrical research could be both serious inquiry and unforgettable public theater.
