Working in the late 18th and early 19th Centuries, Count Alessandro Volta (1745-1827) was another of those figures who advanced several scientific fields in the heady days of the Age of Enlightenment.
While his work as a physicist (including discovering methane gas) was important, he is best known today for chemistry, especially its relation to electricity.
Hence, drawing on his education from a variety of fields, in 1800 Volta developed the first electric battery able to produce a steady current.
As others built on this breakthrough, they needed new words to talk about electricity. And so, in honour, his surname dropped its a and became a fundamental piece of scientific terminology.
