Sir Alistair Allan Horne CBE FRSL (born 9 November 1925) is a British journalist, biographer and historian of Europe, especially of 19th and 20th century France. He is a son of Sir Allan Horne (died 1944) and Auriol (née Hay-Drummond), niece of the 13th Earl of Kinnoull.
Youth and education 
As a boy during World War II, Horne was sent to live in the United States. He attended Millbrook School, where he befriended William F. Buckley, Jr., who remained a lifelong friend. Horne served in the RAF in 1943–44 and later as an officer in the Coldstream Guards from 1944–1947. He graduated from Jesus College, Cambridge as a Master of Arts (MA) and in 1993 received the degree of LittD from the University of Cambridge.
He is the biographer of British Prime Minister Harold Macmillan, a work originally published (in two volumes) in 1988 and author of the authorised biography of former U.S. Secretary of State Henry Kissinger (author's statement, Paris, 13 June 2008).
Following the 2003 US invasion of Iraq, Horne's 1977 book A Savage War of Peace: Algeria 1954-1962 came to be of much interest to American military officers, having been recommended to U.S. President George W. Bush by Dr Henry Kissinger. In October, 2006 the book was republished and in January 2007, by phone from his home in England, Sir Alistair was invited to take part in an Iraq War discussion panel on the Charlie Rose Show on PBS.
Summoned to the Bush White House 
It was reported, in the 2 July 2007 edition of the Washington Post, that Horne met with President Bush sometime in mid-2007 at the administration's request. Staff writer Peter Baker relays that they discussed philosophy and history; he also quoted Horne to have said that, "You think about Prime Ministers and Presidents being surrounded by Cabinet officials and aides and so forth, but at the end of the day, they're alone. They're lonely. And that's what occurred to me as I was at the White House. It must be quite difficult for him (George W. Bush) to get out and about." He described his visit in a Daily Telegraph article.

- (speaking of aerial combat in World War I) "Never since the Middle Ages and the invention of the longbow had the battlefields of Europe seen this kind of single combat. When the champions of either side met to fight spectacular duels in and out of the clouds, the rest of the war seemed forgotten; even the man in the trenches paused to watch, as the hosts of Greece and Troy stood by when Hector and Achilles fought."

- "On the whole, my sympathies have instinctively been with Israel."
- The Daily Telegraph, 4 August 2006.
- "Bush, an honourable man, might have made a good President - without Iraq. His fault was to heed too often the voices of the Zionist lobby in Washington. Never before has the Israeli tail wagged the American dog quite so vigorously; the results threaten to prove as disastrous for Israel as for the Western alliance."
