National Coming Out Day was founded in the United States in 1988 by Robert Eichberg, a psychologist, and Jean O'Leary, an openly lesbian political leader and activist. Eichberg, who passed away from complications related to AIDS in 1995, emphasized self-acceptance and positivity as the core tenets of coming out.
The date of October 11th was chosen because it marks the anniversary of the 1987 National March on Washington for Lesbian and Gay Rights, a significant event that mobilized hundreds of thousands of people. The founders believed that visibility was key to progress, based on the idea that people are far less likely to maintain homophobic or transphobic attitudes if they know and care about someone who is LGBTQ+.
The Human Rights Campaign (HRC) now sponsors NCOD events and provides resources under the theme "Coming Out: Living Authentically."
