Celebrate the 25th Anniversary of the Jean-Nickolaus Tretter Collection in GLBT Studies housed in the Archives and Special Collections at the University of Minnesota Libraries. Since Jean first donated his personal collection to the Libraries in 2000, the Tretter Collection has been rapidly growing its holdings to represent a vibrant and diverse record of LGBTQ history.

This exhibit celebrates the historical visibility and representation discoverable in the Tretter Collection by displaying the breadth of ephemeral materials we preserve. An avid collector of LGBTQ materials since the 1970s, Jean — and his legacy — has enabled this queer and trans archives to flourish, capturing our community’s history here in the Midwest, across the United States, and abroad. Collectively, the history that the Tretter Collection holds evidences a longstanding, resilient LGTBTQ community that has endlessly found ways to remain indivisible.
