During World War 1 the president was Woodrow Wilson.
Woodrow Wilson I believe that's the right answer ;
Woodrow Wilson was the President of the United States during World War I from 1914 to 1918. He initially maintained a policy of neutrality but later led the U.S. into the war in 1917. After the war, he played a key role in the peace negotiations and the establishment of the League of Nations.
