Our collections span centuries and include objects related to protest and politics, medicine and psychology, love and marriage, sports and entertainment, and more. Sometimes, curators and archivists collected objects for a specific reason that later turned out to have LGBTQ+ connections. For example, the numismatics collection has coins that were collected decades ago with the likenesses of emperors and royalty, such as Queen Christina of Sweden, who expressed same-sex attraction. Identities, terms, and definitions related to sexual orientation and gender identity have been in flux as long as there have been humans. The museum is continually adding to and mining our existing resources in order to better understand evolving and overlapping identities such as lesbian, gay, bi-sexual, transgender, queer, transsexual, transvestite, mahu, homosexual, fluid, invert, urning, third sex, two sex, gender-bender, sapphist, hijra, friend of Dorothy, drag queen/king, and many other experiences.
