Museums

Located on Mueller Company grounds, the museum celebrates the accomplishments of inventor Hieronymus Mueller, Decatur's "Unsung Genius" and holder of over 500 patents.

The Mueller Museum celebrates the life and legacy of Hieronymus Mueller, who emigrated from Germany to Decatur, Illinois, and founded several business concerns, including Mueller Co., which still exists today and produces many of the original signature Mueller products, namely water pressure valves and the iconic fire hydrants that we see in nearly every American town and city. Among the expanded facility's treasures: The seventh of only eight cars manufactured by Mueller!
