Oswald John Frederick Crawfurd CMG (18 March 1834 – 31 January 1909) was a British journalist, man of letters and diplomat.
Oswald John Frederick Crawfurd was born at Wilton Crescent, London, on 18 March 1834.
An ultimatum from Lord Salisbury in January 1890, the result of the occupation by Portuguese troops of British territory in East Africa, led to an outburst of anti-British feeling, more violent in Oporto than in other Portuguese towns.
Crawfurd's house was stoned, but he carried on his duties till the trouble subsided, and then on 17 June 1891 he resigned and returned to England.
He remarried at the English Church in Paris on 18 September 1902 to Lita Browne, daughter of Hermann von Flesch Brunnigen, an Imperial Counsellor at Vienna.
