But in his classic study of the x-ray spectra of elements, he established the truly scientific basis of the Periodic Table by arranging chemical elements in the order of their atomic numbers. Henry Gwyn Jeffreys Moseley, who was always called Harry by his family, was born in Weymouth, England, on November 23, 1887.
