Galvani

 was a scientist who explored electromagnetic forces in living beings.

He was able to make frogs' legs move by subjecting them to electromagnetic spark. ( AUDIO :  Mary's Story )

Inspired by Galvani's experiments, Percy Shelley suggested to connect a lightning rod with the apparently dead body of the Eighth Doctor during a thunderstorm to see what will happen. As the result of this experiment, the Doctor was resurrected back to life but transformed into a violent monster. (AUDIO: Mary's Story)
