John Alexander Reina Newlands (26 November 1837– 29 July 1898) was an English chemist who worked on the discovery of the Periodic Table of the Elements. He studied at the Royal College of Chemistry in London. 
He arranged the chemical elements according to their atomic weight. He noticed a pattern with every eighth element, which he compared to octaves in music. He called this the Law of Octaves.
