About Us

The museum was first envisioned by community partners and staff for the University of Wisconsin Oshkosh Fox Cities Campus (formerly UW-Fox Valley). The initial design and layout of the Weis Earth Science Museum came from founding director Dr. Joanne Kluessendorf. The museum officially opened to the public on November 13th, 2002. During construction, generous donations and assistance were provided by geologists Sally and Gene LaBerge, Richard Seidler, John Barlow, and Clyde Stephenson. The museum is named for Leonard and Donna Weis, who provided the founding financial gift to establish the museum and to endow the director’s position. Former Governor Tommy Thompson designated the museum as the Official Mineralogical Museum of Wisconsin in 2000.

Since its opening, the museum has provided educational programming to tens of thousands of students from across the state and has hosted internationally recognized speakers and events, such as the Wonderful World of Agates Conference in 2008. Over the years, the museum collections have grown as the result of further donations and support from members of the Fox Cities community. The museum looks to continue this growth going forward, providing unique educational experiences for the public to enjoy for decades to come.
