Claim to Fame:
Brønsted was a Danish chemist best known for his proton theories of acids and bases. He developed his theory at the same time as a similar theory proposed by English chemist Thomas Lowry so the theory is generally known as Bronsted-Lowry acids. It suggests acids are solutions that donate protons to bases in acid/base reactions. He also made several contributions to the understanding of the catalytic action of acids and bases.
