History

Dubois County was formed on December 20, 1818, from Orange, Pike and Perry counties. It is named for Toussaint Dubois, a Frenchman who fought in the American Revolutionary War, the Battle of Tippecanoe and the War of 1812. Dubois was a merchant who lived mainly in Vincennes. He drowned in 1816 while crossing the Little Wabash River near Lawrenceville, Illinois.

In 1818, as many as half of the residents of the county died of milk sickness. The plant contains the potent toxin temetrol, which is passed through the milk. The migrants from the East were unfamiliar with the Midwestern plant and its effects.

Dubois County switched to the Central Time Zone on April 2, 2006, and returned to the Eastern Time Zone on November 4, 2007; both changes were controversial as Huntingburg wished to remain on Central Time while Jasper never wanted to leave Eastern Time.

The original county seat was Portersville. In 1830, the county seat was moved south to Jasper.
