Sir Mansfeldt de Cardonnel Findlay (7 April 1861 – 31 December 1932) was a British diplomat who had the difficult task of envoy to Norway during World War I. Findlay was educated at Harrow School and joined the Diplomatic Service as an Attaché in 1885.
He was Minister Resident at Dresden and Coburg 1907–09,[1] and Envoy Extraordinary and Minister Plenipotentiary at Sofia 1909–11[2] and at Christiania 1911–23,[3] including the important period of World War I. R. H. Bruce Lockhart described Findlay as "one of the tallest Englishmen in the world and certainly the tallest man in diplomacy.
"[4] In October 1914 Sir Roger Casement, an Irish nationalist, travelled to Germany via Norway with a companion named Adler Christensen.
[6] British records suggest that Christensen approached the British Legation voluntarily with a plan to betray Casement, was given a small amount of money, and was offered a large amount for information that would lead to Casement's capture.
[7] Mansfeldt Findlay was appointed CMG in 1904,[8] CB in 1908,[9] knighted KCMG in 1916[10] and given the additional knighthood of GBE in 1924 on his retirement.
