While he may not be well-known on this side of the pond, Harold Wilson was a British politician who served as Prime Minister of the United Kingdom twice, from 1964 to 1970 and again from 1974 to 1976. In total, he won four general elections, spending nearly eight years in Downing Street. Meanwhile, another Wilson you are more likely familiar with is Woodrow Wilson, the 28th President of the United States. As president, Woodrow Wilson led the United States through World War I, negotiated the Treaty of Versailles, and founded the League of Nations.
