Schomberg Henry Kerr, 9th Marquess of Lothian, (2 December 1833 – 17 January 1900), styled Lord Schomberg Kerr until 1870, was a British diplomat and Conservative politician. He served as Secretary for Scotland under Lord Salisbury between 1887 and 1892. He was usually styled simply as Lothian. Background and education Lothian was the second son of John Kerr, 7th Marquess of Lothian, and Lady Cecil Kerr. His younger brothers Major-General Lord Ralph Kerr (1837–1916) and Admiral of the Fleet Lord Walter Kerr (1839–1927) both had distinguished military careers. He was educated at Trinity College Glenalmond, now Glenalmond College Perth, and was one of the first of 14 boys to join the newly started school in 1847. He later went to Eton College before attending New College, Oxford. He did not graduate. Diplomatic and political career Lothian entered the Diplomatic Service and was an attaché at Lisbon and Tehran in 1854, Baghdad in 1855 and Athens from 1857, then second secretary at Frankfurt from 1862, Madrid from 1865, and Vienna from 1865. In 1870, he succeeded to the marquessate on the early death of his childless elder brother, and took his seat in the House of Lords. In 1886, he was sworn of the Privy Council, and the following year he succeeded Arthur Balfour as Secretary for Scotland and Vice-President of the Scottish Education Department in Lord Salisbury's Conservative administration. However, in contrast to Balfour, he was not a member of the cabinet. He remained as head of the Scotland Office until the government fell in 1892. Apart from his political career, Lord Lothian was Keeper of the Privy Seal of Scotland from 1874, a post he held until his death 26 years later, and was also Keeper of the Great Seal of Scotland while Secretary for Scotland. In 1878, he was created a Knight of the Thistle, and in 1882 he received an honorary degree (LL.D.) from the University of Edinburgh. The students of the same university elected him Rector of the University of Edinburgh between 1887 and 1890. He was a Trustee of the Board of Manufactures in Scotland until his death. He was Captain-General of the Royal Company of Archers, president of the Society of Antiquaries of Scotland (1876-1890) and Royal Scottish Geographical Society (1894-1898), and a Knight of Grace of the Venerable Order of Saint John of Jerusalem.
