Brønsted, Johannes

[person]

Danish physical chemist born in Varde (1879-1947). In 1906, Brønsted published his first paper on electron affinity. In 1923, he suggested the protonic theory of acid-base reactions, and later became an authority on catalysis by acids and bases. The Brønsted catalysis equation is named for him. He also developed the theory of proton donors during ionization.
