Tums Building
Downtown
Architect: Widmer Engineering Company
Date: 1933

Perhaps the first Modernist building in downtown St. Louis, the Tums factory was groundbreaking in its simplicity. Art Deco influences can be seen in its sparse decoration, but the overall design is pure International Style, with alternating ribbons of windows and brick forming continuous bands around the facade. The tower acts as an accenting vertical element. At the other end, a second vertical component appears to be an earlier building, appearing on a vintage postcard without the International Style section.

The Modernist addition to the Tums factory went up when the brand was only three years old. The building complex is still the world headquarters for the Tums brand, and churns out billions of the antacid tablets every year.
