Roger Casement - Wikipedia

Roger Casement (1864-1916) was originally a diplomat who worked for the British Foreign Office and a human rights investigator, having uncovered abuses in the Congo and Peru. Disillusioned with British imperialism, he gradually converted to Irish republicanism and was principally responsible for organising negotiations with Germany for foreign aid, although remained unaware of the Easter Rising until very late. He was ultimately arrested in County Kerry, having returned from Germany, in the early hours of 21 April 1916, and charged with high treason and sabotage against the Crown. He was executed on 3 August 1916 at Pentonville Prison, London.
