Ingersoll was founded in 1977 by
Marsha C. Botzer and gained non-profit status in 1984. One of the reasons Botzer has cited for founding the organization is a problem of joblessness and
underemployment of transgender people. Botzer is quoted in the 2021 book
Going to Trinidad by journalist Martin J. Smith that in the early years of the center she would tuck Ingersoll Center business cards between the pages of books in the
Seattle Public Library's small collection of books on the subject of gender as an attempt to get the word out about the center's services in the pre-Internet era. The primary service provided by Ingersoll is support groups led by local transgender and gender non-conforming people for their peers who are in need of support. Another service the organization provides is helping individuals access
gender affirming healthcare and navigate their health insurance. In 2012, the organization launched a program for vocational support called Seattle Transgender Economic Empowerment Project (STEEP). Later that year the proposal was made law as the All Gender Restroom Ordinance. This made Seattle one of the first U.S. cities to enact such a law. After
Donald Trump became
President of the United States, Ingersoll Gender Center started publishing annual voter's guides with the first being for 2017. At the start of 2017,
University of Washington School of Medicine launched a program to focus on training doctors in LGBTQ+ healthcare with collaboration and consulting from the gender center. The group lobbied for
Washington state to allow the gender marker "X" option on driver's licenses and identification cards, which became state policy in November 2019. The organization has also worked with local real estate developers on an affordable housing project in the historically LGBTQ
Capitol Hill neighborhood for seniors. Also in 2019, Botzer was appointed to a
King County Council task force as a representative of Ingersoll Gender Center. The purpose of the task force was to "spread awareness and understanding of gender nonconforming individuals and their experience with county departments and facilities". Part of the city of Seattle's early relief efforts was to distribute grocery store vouchers to residents who had lost work due to the pandemic. The city gave some vouchers to organizations, including Ingersoll Gender Center, to distribute within their communities to impacted families and individuals. In 2021 the
Seattle Police Department was banned from participating in Capitol Hill Seattle Pride's march, and some gay cops said that they felt excluded from the Pride event. Botzer suggested a potential strategy to create solidarity between police and the
LGBT community would be for the police department to hire more transgender cops, which she argued would reduce the accounts of police violence against transgender people. == Controversies ==
