The first steamboat on the Mississippi, and appropriately so, was "The City of New Orleans," built by Nicholas Rosevelt, a kin to FDR. First trip down the Mississippi, from Chicago to New Orleans, was made by a Jesuit, one Jacques Gravier, early in the 18th Century.

Legendary river characters are "Mike Fink," a strong man, and "Annie Christmas," a strong woman, both of whom performed incredible feats of prowess. More of the same is "Old Al," a giant alligator, called "The King of the River." and often referred to by river people even today. Another of the more famous legends concerns the river's water and how it's supposed to be a guarantee against sterility in humans. It was once even bottled and sold with that recommendation.
