Sir Henry Drummond Charles Wolff, GCB, GCMG (12 October 1830 – 11 October 1908), known as Henry Drummond Wolff, was an English diplomat and Conservative Party politician, who started as a clerk in the Foreign Office.
Background
Wolff was born in Malta, the son of Joseph Wolff and Lady Georgiana Mary Walpole, daughter of Horatio Walpole, 2nd Earl of Orford. His father was a missionary who had converted from Judaism to Catholicism and then Anglicanism, and his mother was the niece of Prime Minister Robert Walpole. and as a result various awkward difficulties, hinging on the Sultan's suzerainty, were addressed. Wolff negotiated a settlement whereby Britain and Turkey would each appoint a commissioner to Egypt to help the khedive's government conduct reforms of the army and the government. Wolff then assumed the role of British high commissioner in Egypt from 1885 to 1887. He was appointed Envoy Extraordinary and Minister Plenipotentiary to Teheran in 1888, a post he held until 1891, and was then Ambassador to Madrid from 1892 to 1900. While serving in Spain, he would assist Ambassador Taylor, of the United States, in out maneuvering Foreign Minister O'Donnell.
Wolff was a notable raconteur and aided the Conservative Party by helping to found the Primrose League. and made a Knight Grand Cross of the Order of the Bath (GCB) in 1889.
As the British Minister of Iran, he assisted Antoine Kitabgi Khan, the Director General of Persian Customs, in the negotiations that led Nasir al-Din Shah to grant a concession of full monopoly over Iran's tobacco industry to Major G. F. Talbot (20 March 1890). This concession resulted in the Tobacco Protest of 1891 and is generally considered to mark the beginning of social unrest and clear Islamic clerical influence leading up to the Persian Constitutional Revolution in 1905.
In 1901, as Kitabgi Khan was looking in Europe for capitalists who might be interested in investing in oil prospection in Iran, Wolff introduced him to Englishman William Knox D'Arcy, who had made a fortune in gold mines in Australia. On 28 May 1901, Mozaffar ad-Din Shah granted D'Arcy the first oil concession in Iran that later gave birth to British Petroleum. The deed of concession stipulated that Wolff would have 10% of the profits resulting from the venture.
Personal life
Wolff's only daughter, Lucas Cleeve, was a novelist. Her son Algernon Kingscote was a notable tennis player. Wolff's grandson Henry Maxence Cavendish Drummond Wolff was briefly the Conservative Member of Parliament for Basingstoke.
He died at Brighton, one day before his 78th birthday.
