Hieronymus Mueller Museum | Decatur, Illinois

Welcome to the Hieronymus Mueller Museum, just west of downtown Decatur, Illinois, and open to the public on Tuesday through Saturday and other times by appointment.

The Mueller Museum is dedicated to the collection, preservation, and interpretation of the history of Mueller Company and of the family and descendants of Hieronymus Mueller

The Mueller Museum celebrates the life and legacy of Hieronymus Mueller, a pioneer entrepreneur 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.

The Hieronymus Mueller Museum was founded in 1995 by the Hieronymus Mueller Family Foundation to house and curate the vast collection of Mueller Family and Mueller Co physical artifacts, memorabilia and library materials. The museum moved to its present home in 2005, a state-of-the-art facility to preserve and display the historically-significant collection.

The story of Hieronymus Mueller is like the stories of hundreds of thousands of immigrants who were driven to America by the dual forces of opportunity and necessity – the necessity to escape famine, political oppression, religious intolerance, or economic disasters. He made the most of his opportunity and became a quintessential immigrant success arriving with pennies in his pockets while going on to achieve the “American Dream.”

This week, the Hieronymus Mueller Museum and The Staley Museum, our sister museum, had the pleasure of hosting the Decatur Christian School's 4th graders. We had a lot of fun sharing Decatur's local history and introducing them to two different types of museum experiences!
