About One

Founded in 1952, One Institute (formerly ONE Archives Foundation) is the oldest active LGBTQ+ organization in the country, dedicated to telling LGBTQ+ history and stories through education, arts, and social justice programs. Our one-of-a-kind exhibitions and public programs connect LGBTQ+ history and contemporary culture to effect social change. Through unique K-12 teacher trainings, lesson plans, and youth mentorship programs, we empower the next generation of teachers and students to bring queer history into classrooms and communities. As the independent community partner of ONE Archives at the USC Libraries, we promote the largest collection of LGBTQ+ materials in the world.

The curatorial and educational choices made by One Institute are guided by our commitment to social equity and justice. We engage with the complexity of LGBTQ+ history and representation through highlighting the intersectional narratives of Black, Indigenous, people of color (BIPOC), women, gender- nonconforming and transgender people, people of various abilities, youth, and elders across all socio-economic classes.

Value Statement

Out of our commitment to social equity and justice, we tell the stories of the LGBTQ community and its history. We engage with the complexity of queer history and representation through highlighting the intersectional and authentic narratives of Black, Indigenous, people of color (BIPOC), women, gender-nonconforming and transgender people, people of various abilities, youth, and elders across all socio-economic classes.  

We work in partnership both within our community and outside it in ways that foster trust and long-term relationships among groups. We seek to encourage understanding and empathy among our constituents in order to build coalitions and create social change.


We envision a world motivated by social movements of the past to take action toward queer and trans liberation.


One Institute elevates queer and trans histories and embraces emerging stories through collaborative education, arts, and cultural programs.

In October 1952, several members of the Mattachine Society, including educator and activist W. Dorr Legg, formed ONE, Inc.. In January 1953, ONE, Inc. published the inaugural issue of ONE Magazine, the first widely distributed LGBTQ+ publication in the United States.

The Los Angeles postal authorities seized the August 1953  and October 1954 issues of ONE Magazine on charges of obscenity simply for publishing articles, editorials, short stories, book reviews, and letters to the editor from a queer perspective. ONE, Inc. decided to fight these charges.  

Four years of litigation with the postal authorities brought the ONE Magazine case to the nation’s highest court. In 1958, the landmark Supreme Court case, ONE, Inc. v. Olesen, determined that ONE Magazine was not in violation of obscenity laws, becoming the first ruling to deal with homosexuality and the first to address free speech rights with respect to LGBTQ+ people.

In 1956, while still in litigation, ONE, Inc. founded One Institute as the educational arm of the organization. One Institute conducted seminars, published a journal, and eventually issued graduate degrees in “Homophile Studies,” demonstrating that queer and trans lives and communities were worthy of serious scholarly work.

All throughout this time, Jim Kepner, a frequent contributor to ONE Magazine and co-founder of One Institute, thoughtfully collected material related to LGBTQ+ topics, issues, and individuals. Kepner’s personal collection over the course of his life and in 1994, this collection merged with ONE Institute. This collection was donated to USC in 2010. Today, ONE Archives at USC Libraries is the largest repository of LGBTQ+ materials in the world.

In 2014 our organization renamed itself as ONE Archives Foundation and began to build robust programming that amplified the collections at ONE Archives at USC Libraries as well as developed unique K-12 educational programs and arts & cultural events related to queer and trans history.  

Today, we’ve gone back to our 1950’s roots to reclaim “One Institute” as our nonprofit organization’s name with the tagline “Queer and Trans History in Action,” reflecting our present-day goals of education, advocacy, and cultural enrichment.
