Officially known as the Louisiana Purchase Exposition, the St. Louis World's Fair introduced our city on an international stage. The event was centralized in Forest Park, and it was no easy task to bring together. David K. Francis, a former Mayor of St. Louis and Governor of Missouri, was the driving force behind promoting our city as the site of the exposition. The World's Fair and the Summer Olympics, which were held that same summer, changed St. Louis forever. See below the stunning images of this huge event in our history.

Nefarious as it sounds, these displays were officially called "Ethnological Expositions," and were a common sight at fairs and zoos across the world. The people of the "Human Zoo" were most often on display in replicas of their homeland living spaces. How well a group was treated in exhibitions depended largely on the attitudes of the event promoters and the social status of the group on display.

People came from all over the world to attend the St. Louis World's Fair. The official attendance count was 19,694,855! The fair brought both money and work to the St. Louis region and many people who came to work at the fair stayed in St. Louis permanently.

The St. Louis World's Fair was held from April 30th to December 1st, 1904. The promoters of the event billed it as educational and informative, but unlike other World's Fairs, most of the technology displayed was already in use. The St. Louis World's Fair was more of a showcase than a debut, but people flocked to the city to see things they had only ever heard existed.

Some consider the St. Louis World's Fair the birthplace of many inventions, including ice cream cones, ice tea, sliced bread, and more. Do you know of any interesting stories from this incredible event in St. Louis history? Share them with us in the comments below!
