- Luigi Galvani, Alessandro Volta, Humphry Davy, and Michael Faraday were all scientists whose work in the late-eighteenth and nineteenth centuries increased understanding of electron transfer reactions.

- The complete understanding of electron transfer reactions in terms of ions and electrons was not fully developed until the end of the nineteenth century.
- The contribution of these four scientists allowed Arrhenius to later develop the ionic theory of solutions.
- Arrhenius theory, coupled with Thomson’s discovery of the electron, allowed chemists to fully understand electron transfer electrons.
