Ernest Mason Satow, English orientalist and diplomat (d. 1929)

Sir Ernest Mason Satow, (30 June 1843 – 26 August 1929), was a British scholar, diplomat and Japanologist.Satow is better known in Japan than in Britain or the other countries in which he served, where he was known as Satō Ainosuke (Japanese: 佐藤 愛之助/薩道 愛之助). He was a key figure in East Asia and Anglo-Japanese relations, particularly in Bakumatsu (1853–1867) and Meiji-period (1868–1912) Japan, and in China after the Boxer Rebellion, 1900–06. He also served in Siam, Uruguay and Morocco, and represented Britain at the Second Hague Peace Conference in 1907. In his retirement he wrote A Guide to Diplomatic Practice, now known as 'Satow's Guide to Diplomatic Practice' – this manual is widely used today, and has been updated several times by distinguished diplomats, notably Lord Gore-Booth. The sixth edition edited by Sir Ivor Roberts was published by Oxford University Press in 2009, and is over 700 pages long.
