#28 Woodrow Wilson 
"The World must be made safe for democracy." Pres. Woodrow Wilson on declaring war on Germany, April 6, 1917
German submarine attacks on U. S. shipping brought an end to American neutrality during World War I. At the time, it was a common for families to have Victory Gardens to grow food for the home front. Instead of the usual presidential pets of dogs or cats, Wilson's White House boasted a small flock of sheep. The sheep, Wilson's gift to his wife Edith, both trimmed the White House grass and provided wool. The "White House wool" raised almost $100,000 for the Red Cross at auction.
For his efforts in ending World War I and creating the League of Nations, a precursor to the United Nations, Wilson was awarded the Nobel Peace Prize in 1920.
