Mission
TO INSPIRE PEOPLE OF ALL AGES TO DISCOVER AND APPRECIATE THE RICH HISTORY AND NATURAL WORD IN THE FOX VALLEY AREA.
Program accomplishments
- FOUNDED IN 1872 AS A PIONEER ASSOCIATION, THE OUTAGAMIE COUNTY HISTORICAL SOCIETY INSPIRES PEOPLE TO DISCOVER AND APPRECIATE THE RICH HISTORY AND NATURAL WORLD IN THE FOX VALLEY THROUGH EXHIBITION, EDUCATION, AND COLLECTIONS. NOW AFFECTIONATELY KNOWN AS THE HISTORY MUSEUM AT THE CASTLE, DUE TO ITS LOCATION IN A FORMER MASONIC TEMPLE, THE ORGANIZATION IS A THRIVING CULTURAL INSTITUTION WITH DEEP TIES TO THE LOCAL COMMUNITY. THE HISTORY MUSEUM AT THE CASTLE EXPANDED ITS MISSION IN 2025 TO INCLUDE NATURAL HISTORY. TO FACILITATE THAT ADDITION, THE HISTORY MUSEUM HIRED TWO MUSEUM SPECIALISTS AND INCORPORATED THE WEIS EARTH SCIENCE COLLECTION, CONSISTING OF 38,054 SPECIMENS, INTO ITS REGULAR OPERATIONS. BY PRESERVING THE WEIS EARTH SCIENCE COLLECTION LOCALLY, THE PUBLIC WILL CONTINUE TO HAVE ACCESS TO LIVELY EARTH SCIENCE EXHIBITIONS AND PROGRAMMING THAT BENEFIT FOX VALLEY RESIDENTS, SCHOOLS, AND UNIVERSITIES. ADDING THE WEIS COLLECTION TO THE HISTORY MUSEUM'S DYNAMIC LOCAL HISTORY OFFERINGS IS ALSO EXPECTED TO GROW THE REGION'S TOURIST ECONOMY. IN ADDITION, THE HISTORY MUSEUM CONTINUED TO ENGAGE AUDIENCES WELL BEYOND ITS WALLS. THE MUSEUM SUPPORTS A SERIES OF FREE TRAVELING POP-UP EXHIBITS ON RELEVANT LOCAL HISTORY TOPICS. IN 2024 THE MUSEUM ADDED OUR AFGHAN NEIGHBORS TO THAT CATALOGUE OF EXHIBITS. WORLD RELIEF FOX VALLEY AND THE HISTORY MUSEUM PARTNERED TO CONDUCT ORAL HISTORY INTERVIEWS WITH EIGHT AFGHAN REFUGEES FORCED TO FLEE AFGHANISTAN IN 2021 AND RESETTLE IN THE FOX CITIES. THEIR STORIES BECAME THE BASIS FOR THIS GROUNDBREAKING EXHIBITION. THE EXHIBIT TOURED THROUGHOUT NORTHEAST AND CENTRAL WISCONSIN IN 2025. APPROXIMATELY 149,430 PEOPLE VIEWED OUR AFGHAN NEIGHBORS, INCLUDING STOPS AT THE HOLIDAY FOLK FAIR IN MILWAUKEE AND THE STATE CAPITAL IN MADISON. IN PURSUING OUR MISSION, THE BOARD OF DIRECTORS, STAFF, AND VOLUNTEERS FOSTER COMMUNITY PARTNERSHIPS THAT BUILD SOCIAL COHESION AND MEET LOCAL CHALLENGES. DOING SO EXPANDS EXPECTATIONS FOR WHAT A MUSEUM, AND OUR COMMUNITY, CAN BE.Expenses $565,015 · revenue $110,432
