The 1933 World’s Fair was headlined the "Century of Progress," celebrating the 100 years of Chicago's existence and the progress of science and industry during that time. The fairgrounds on the lakefront, known as Rainbow City, featured a colorful, futuristic design that introduced many to the Modernist architectural movement. Thirty-nine million visitors marveled at the new technologies and experimental materials, including the first dishwasher and central air conditioning in a home. Most importantly, baseball’s first All-Star Game was held in conjunction to the Fair.
