Biography Moseley, Henry Gwyn Jeffreys
(1887-1915)
Born in Weymouth (Dorset) 23 November 1887. He studied at Eton and Trinity College, Oxford University. In 1910-1914 he worked in Rutherford's laboratory at Manchester University, then at Oxford University. In 1913, established the relationship between the frequency of the spectral lines of the characteristic X-rays and atomic number of the radiating element. By law Moseley, 'the square root of the frequency of the corresponding lines in the X-ray spectra of various elements increases when moving from the element to the next one and the same value'. This discovery was of great importance to establish the physical meaning of the periodic table of elements and the atomic number. In 1914 Moseley published a paper which concluded that among the elements of aluminum and gold in the periodic table must be three (as it turned out later, four) elements. Since the beginning of the First World War, Moseley was sent to the front. Moseley died at Gallipoli (now Gelibolu, Turkey), August 10, 1915.
