All the queen's presidents: From Truman to Obama

Since Elizabeth II came to the throne in 1952, 10 U.S. presidents have been elected. The UK's queen has met all of them, with the exception of Lyndon B. Johnson. She would have met President Johnson during the funeral of President John F. Kennedy but was pregnant with her third son, Edward, at the time and could not make the trip. Before her coronation she met serving president Harry Truman and during her reign also met former president Herbert Hoover.
