The Emperor Napoleon I of France, as well as American presidents Franklin D. Roosevelt, and Herbert Hoover, all feared the number 13. Roosevelt wouldn't travel on the 13th day of any month.
Part of the superstition about the number 13 stems from the fact that the number falls after the oft-used number 12. There are 12 months, 12 days of Christmas, 12 tribes of Israel and 12 signs of the zodiac
