Moseley, Henry Gwyn-Jeffreys 

Born Nov. 23, 1887, in Weymouth, England; died Aug. 10, 1915, at Gallipoli (present-day Gelibolu), Turkey. British physicist.

Moseley studied at Trinity College and Oxford University, graduating in 1910. From 1910 to 1914 he worked first at the University of Manchester and then at Oxford University. In E. Rutherford’s laboratory (at Manchester), Moseley conducted studies in beta-ray, gamma-ray, and X-ray spectroscopy. In 1913 he established the relation between the frequency of the spectral lines of characteristic X-radiation and the atomic number of the element (Moseley’s law.) He was killed in action during World War I.
