Svante August Arrhenius, a founding father of physical chemistry, was trained both in chemistry and physics. Born in 1859, Arrhenius studied at the University of Uppsala and the Swedish Academy of Sciences in Stockholm. He was best known for his theory that electrolytes, certain substances that dissolve in water to yield a solution that conducts electricity, are separated, or dissociated, into electrically charged particles, or ions, even when there is no current flowing through the solution.
Svante August Arrhenius died in 1927.
