Robert Gilbert Vansittart (raised to the peerage as Baron Vansittart of Denham in 1940), was not a German. He was born in 1881 in Farnham (Surrey) and educated at Eton. He served as First Secretary of the Paris Peace Conferrence in 1919-1920. He was indeed an extreme Germanophobe (and extreme Germanophobia became known in England as "vansittartism") but after Chamberlain forced him out of his post as permanent under secretary at the Foreign Office and relegated him to a sinecure Vansittart was not really in a position to have much influence on British policy although some of the more Germanophoic policy makers in both the UK and the USA may have been influenced by his writings.
