He received a degree in chemical engineering in 1899 and his Ph. D. in 1908 from the University of Copenhagen. He was immediately appointed professor of inorganic and physical chemistry at Copenhagen.

In 1906 he published his first of many papers on affinity. In 1923 he introduced the protonic theory of acid-base reactionsAn acid-base reaction is a chemical reaction between an acid and a base. Common acid-base theories The Arrhenius definition Svante Arrhenius provided the first modern definition of acids and bases in 1884. In water, a dissociation takes place: :HO →, simultaneously with the EnglishEngland is the largest, the most populous, and the most densely populated of the four " Home Nations" which make up the United Kingdom of Great Britain and Northern Ireland (UK). Occupying the south-eastern portion of the island of Great Britain, England chemistA chemist is a scientist who specializes in chemistry. The word derives from the older term alchemist. Also, in British English, the term is used for a pharmacist or a pharmacist's shop. See also: List of chemists, Nobel Prize in Chemistry, Biography. Thomas Martin LowryThomas Martin Lowry ( October 26, 1874- November 2, 1936) was an English physical chemist. He was born in Low Moor, Bradford, West Yorkshire, England. He studied chemistry under Henry Armstrong, an English chemist whose interests were primarily in organic. The same year, the electronThe electron (also called negatron commonly represented as e&minus is a subatomic particle. In an atom the electrons surround the nucleus of protons and neutrons in an electron configuration. Electrons have the smallest electrical charge and when they movic theory was proposed by Gilbert N. LewisGilbert Newton Lewis ( October 23, 1875- March 23, 1946) was a famous physical chemist. Early life Lewis was born in Weymouth, Massachusetts as the son of a Dartmouth-graduated lawyer/broker. He was a precocious child who learned to read at age three., but both theories are commonly used.

He became known as an authority on catalysisIn chemistry and biology, catalysis is the acceleration of the rate of a chemical reaction by a substance, called a catalyst, that is itself unchanged by the overall reaction. A common misunderstanding is that catalysis "makes the reaction happen": that t by acidFor alternative meanings see acid (disambiguation). An acid (represented by the generic formula AH is typically a water-soluble, sour-tasting chemical compound. An acid always has a pH of less than 7. It is a molecule or ion that contains hydrogen or thats and bases.

In World War II he opposed the Nazis, and in consequence he was elected to the Danish parliament in 1947, but could not take his seat because of illness. He died shortly after election.
