Henry Moseley. English physicist Henry Moseley, who arranged the Periodic Table in order of the atomic numbers of the elements. Henry Moseley's research career lasted only forty months before tragically ending with his death on a Gallipoli battlefield in World War I. 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.
