History Monticello was laid out in 1834 as the county seat, with a post office established that year, and is still currently in operation. The city was named after President Thomas Jefferson's estate in Virginia. Monticello, Indiana sustained serious damage by a tornado on April 3, 1974, part of the 1974 Super Outbreak that caused death and destruction across the midwest and south. The aftermath of this storm is recorded in the Herald Journal's book, Killer Tornado. The tornado was rated F4 on the Fujita scale. This storm killed eight people and was part of tornado family that killed 18, causing an estimated $100 million in damage. In the immediate aftermath of the storm, news outlets reported three hundred deaths across the United States and the creation of temporary morgues. The local paper said the aftermath was similar to a World War II bombing. On September 2, 2005, Jordan Manufacturing burned down. The company manufactured outdoor furniture such as folding chairs, umbrellas, and seat cushions. Due to the materials used in making these products, four city blocks were contaminated with toxins. The blaze was large enough to require firefighters from seven surrounding communities to battle it and needed approximately "3000 gallons of water per minute for the first three hours of the blaze." While such a fire might not be a big event for a larger city, it had a profound impact on Monticello, as Jordan Manufacturing was one of the few manufacturing plants left in the city after a recession in the 2000s.
