History of the Mosinee Branch (Joseph Dessert Library)

The Joseph Dessert Library, named after its founder, has been a cornerstone of the Mosinee community for over a century. Joseph Dessert, a Canadian who settled in Little Bull Falls (now Mosinee) in 1844, recognized the need for a library and took it upon himself to build and equip a free library for the community. The library building was dedicated on February 11, 1899, and quickly became a multi-functional space.

Over the years, the library served as more than just a repository for books. It functioned as a post office, village hall, school room, and an event venue for dances, balls, amateur plays, and school commencements. It was also the only place in town with theater facilities, cementing its role as a cultural hub.

Originally a city library, it became part of the Marathon County Public Library system in 1974 following recommendations from the library and municipal boards. Significant anniversaries of the library have been celebrated, including its 50th in 1949 and its 100th in 1999. Renovations have been carried out over the years to preserve and modernize the building, with the most recent updates completed in 1995 as part of a county-wide library building program.

Today, the Joseph Dessert Library remains a vital community resource and a landmark that reflects the rich history and cultural heritage of Mosinee.
