In World War II, Brønsted's opposition to the Nazis led to his election to the Danish parliament in 1947, but he was too ill to take his seat and died shortly after the election.
This led in 1923 to his formulation of the protonic definition of acids and bases, now known as Brønsted–Lowry acid-base theory, independently of the work by Johannes Nicolaus Brønsted.
