Mathiak Collection

The Mathiak Collection of Freshwater Mussels of Wisconsin includes specimens from over 250 rivers and creeks in Wisconsin, provides information regarding the mussel population in Wisconsin over time, and gives rise to future research topics. The collection also features endangered species in the state of Wisconsin such as the Villosa iris, or Rainbow Shell mussel.

Harold A. Mathiak worked for the WI-DNR as a biologist until his retirement. He then spent the next five years doing his freshwater mussel survey across the state, subsequently publishing a book on his findings as a Research Associate at the University of Wisconsin – Stevens Point.
