The Louisiana was a Mississippi River steamboat that exploded on November 15, 1849, killing at least 150 and possibly as many as 200 people, and grievously wounding scores of others.[1] [2] All of the boilers exploded simultaneously about five minutes after she pulled away from the dock at Gravier Street in New Orleans; the entire boat sank 10 minutes after the explosion. Several of the dead were on the steamer Storm, which was docked adjacent to the Louisiana.
