Henry Moseley, remembered

Chemist Henry Moseley should be one of the most celebrated heroes of World War I. He determined what it is about atoms that makes each element distinct, gave us the foundations of spectroscopy and predicted three new elements of his own. But, his life was cut short at the age of 27 by a sniper's bullet at Gallipoli. Justin Wark of Trinity College, Oxford, where Moseley was an undergraduate, told this year’s Synchrotron Radiation User’s Meeting at Diamond that “What Moseley might have achieved is impossible to tell...there is no doubt that within a few short months, the insight he gave us into our world at the atomic level helped define and shape the modern view of how the physical universe operates.”
