The Milwaukee County Historical Society (MCHS)’s photograph collection is one of its key archival collections, alongside county records, manuscript collections, maps, and a small non-circulating library of books. MCHS’s photograph collection documents the history of Milwaukee and Milwaukee County and comprises photographic prints, slides, and negatives. The bulk of the photograph collection documents the 1890s through the 1980s, although older and more recent materials are also represented. The collection is divided into multiple portions, including those corresponding to individual photographers, subjects, and streets in Milwaukee County.
