The Curse of Tippecanoe is the name given to a freakish pattern of presidential deaths.
From William Henry Harrison to John F Kennedy, every president elected on a score year (a year divisible by twenty) died in office.
Tippecanoe was a nickname given to Harrison, the ninth president of United States, after he defeated the Shawnee at the Battle of Tippecanoe in 1811.
