English chemist John A.R. Newlands in 1865.

Explanation:

Law of octaves, in chemistry, is the generalization that if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements.

Newlands was one of the first to detect a periodic pattern in the properties of the elements and anticipated later developments of the periodic law.
