President's Day trivia about America's leaders

President's Day began as a holiday to celebrate America's first president, George Washington, but later evolved to be a day commemorating all of America's presidents - and giving workers a three-day weekend - in 1971. CBSN took a look at some interesting facts about America's past leaders from Smithsonian.com.

• Franklin D. Roosevelt was the first president to name a woman to his cabinet: Roosevelt appointed Frances Perkins as his secretary of labor in 1933. She was previously a social worker who worked in settlement houses in Chicago and Philadelphia. During her tenure at the department, she established the Labor Standards Bureau and was a principal architect of the Social Security Act.
• Warren Harding had the largest shoe size: Size 14. His slippers and golf shoes are still on display at the Smithsonian.
• Theodore Roosevelt wore a lock of Abraham Lincoln's hair during his inauguration: The lock of hair was contained in a ring that was gifted to Roosevelt by John Hay, who worked for Lincoln during his presidency. Roosevelt wore the ring at his second inauguration in 1905. A great admirer of his predecessor, Roosevelt had watched Lincoln's funeral procession pass by his house in New York.
• Gerald Ford was a fashion model in his youth (even appearing on the cover of Cosmopolitan): He was talked into the job by Phyllis Brown, a woman Smithsonian.com describes as his "first love." They appeared together in a ski resort spread of Look magazine in 1940, as well as on the Cosmopolitan cover in 1942. Ultimately, however, she wanted to pursue modeling while he wanted to begin his career as a lawyer, which ended their relationship.
• Four presidents have received the Nobel Peace Prize: Theodore Roosevelt, Woodrow Wilson, Jimmy Carter, Barack Obama. Roosevelt was honored for his work on international peace, including on efforts to broker a peace treaty between Russia and Japan in 1905. Wilson was given the prize in 1919 for his work toward founding the League of Nations after World War I. Carter had already retired from the presidency, but won the Nobel prize in 2002 because of his efforts on human rights resolving international conflicts. Mr. Obama was nominated for "his extraordinary efforts to strengthen international diplomacy and cooperation between peoples," the Norwegian Nobel Committee said at the time.
