In a recent ranking of university museums, The St. Louis University Museum of Art ranked No. 4 in the nation.

Its windows, however, would probably have ranked somewhere near the bottom, which brought added urgency to a recent window replacement project.

But there were challenges. As these are windows in an art museum, they had to contribute to climate control and art preservation. And as part of a historic structure—the one-time home of the St. Louis Club, built in 1900 as the center of St. Louis social life—the windows had to replicate those that stood during visits by several U.S. presidents, including presidents Grover Cleveland, William McKinley, William Howard Taft, Franklin D. Roosevelt, Woodrow Wilson, and Warren G. Harding.
