Freiherr Christian Johann Dietrich Theodor von Grotthuss (January 20, 1785 – March 26, 1822) was a German chemist known for establishing the first theory of electrolysis in 1806 and formulating the first law of photochemistry in 1817.
His theory of electrolysis is considered the first description of the so-called Grotthuss mechanism.
