ENGLISH PHYSICIST
1887–1915

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.

His family was wealthy, aristocratic, and scientifically accomplished, and young Henry showed an early interest in zoology . He attended Eton on a King's scholarship, where he excelled in mathematics, and was introduced to the study of x rays by his physics teacher.

He entered Trinity College, Oxford, in 1906. At that time, Oxford did not have a particularly notable science curriculum, but Moseley chose the school in order to be near his widowed mother. He graduated in 1910
