Henry Moseley, the great X-ray physicist whose discoveries enhanced chemistry too, was honoured at the University of Oxford when the RSC unveiled a plaque to commemorate his work there early in the 20th century.  

Volunteering to fight in the First World War he was killed by the Turks in 1915 during the ill-fated Dardanelles landings at the age of 27. 

In an act of reconciliation the Turkish embassy in London office sent its Minister Counsellor (pictured) to speak at the unveiling ceremony.
