1915 : Henry Ford tries to end Great War
Automobile tycoon Henry Ford set sail for Europe on this day in 1915 from Hoboken, New Jersey, aboard the Ford Peace Ship. His mission: to end World War I. His slogan, "Out of the trenches and back to their homes by Christmas," won an enthusiastic response in the States, but didn't get very far overseas. Ford's diplomatic mission was not taken seriously in Europe, and he soon returned.
PS - Sounds like Ford was a hippy liberal.
