1Many know about Terre Haute's long-gone reputation as a "sin city," but that hardly tells the whole story. Unknown to all but a few, the city was home to a POW camp for Confederate prisoners and divers once plucked valuable freshwater pearls from the Wabash River. Druggist Jacob Baur discovered a way to liquefy carbon dioxide, earning him the title "King of Soda Fountains." Before the advent of Hollywood, motion pictures were made here. And one of the biggest child stars of the 1930s and '40s was a local boy named Billy Lee. He joined another child star from the area, Carl "Alfalfa" Switzer of Our Gang fame. Historian Tim Crumrin reveals the overlooked events and people in Terre Haute's past.
