The World's Columbian Exposition, also known as the Chicago World's Fair, was a very large fair that happened in 1893 to celebrate the 400th anniversary of Christopher Columbus' arrival to the United States.
There were a few recorded notable visitors at this fair, including Alexander Graham Bell and Helen Keller alongside her mentor, Anne Sullivan.
Additionally, Serial killer H. H. Holmes attended the fair with two of his eventual victims, Annie and Minnie Williams.
Mainly, the structures built for the event were not meant to last. However two of the only buildings left standing in Chicago after the fair (in which there were around 200 buildings made) are the Palace of Fine Arts and the World's Congress Auxiliary Building.
The fair included edible treats that we still know of today, such as: cream of wheat, the brownie (which was invented for the fair), Juicy Fruit gum, Quaker Oats, peanut butter, and more.
The fair also included a few inventions such as: the moving walkway, the ferris wheel, the first fully electric kitchen with a dishwasher, a first prototype of aerosol spray, and more.
