Just to prove I did go to Hatfield - the statue of Robert Arthur Talbot who was born at Hatfield House in 1830 and who became the third Marquis of Salisbury. He was three times Prime Minister from 1885 to 1886, 1886 to 1892 and 1895 and 1902. His time as Prime Minister coincided with a great expansion of the British Empire and he is also remembered as an adherent of the policy of "splendid isolation", the desire to keep Great Britain out of European affairs and alliances. he died in 1903.
