Magnus Hirschfeld in the context of Institut für Sexualwissenschaft

The first homosexual movement thrived in Germany from the late nineteenth century until 1933. The movement began in Germany because of a confluence of factors, including the criminalization of sex between men (Paragraph 175) and the country's relatively lax censorship. German writers in the mid-nineteenth century coined the word homosexual and criticized its criminalization. In 1897, Magnus Hirschfeld founded the world's first homosexual organization, the Scientific-Humanitarian Committee, whose aim was to use science to improve public tolerance of homosexuality and repeal Paragraph 175. During the German Empire, the movement was restricted to the wealthy elite, but it greatly expanded in the aftermath of World War I and the German Revolution.

Reduced censorship and the growth of homosexual subcultures in German cities helped the movement to flourish during the Weimar Republic. The first publicly sold, mass-market periodicals intended for a gay, lesbian, or transvestite readership appeared after 1919, although they faced censorship lawsuits and bans on public sale after the 1926 Trash and Smut Law [de]. The first mass organizations for homosexuals, the German Friendship Society and the League for Human Rights, were founded in the aftermath of the war. These organizations emphasized human rights and respectability politics, and they excluded prostitutes and effeminate homosexual men, who were considered harmful to the movement's public image. The homosexual movement had limited success with the general public, in part because many Germans believed that homosexuality could be spread as a communicable disease.

The Scientific-Humanitarian Committee (German: Wissenschaftlich-humanitäres Komitee, WhK) was a transnational advocacy group and civil rights organization founded by Magnus Hirschfeld in Berlin in May 1897, to campaign for the legal rights and social recognition of lesbian, gay, bisexual, and transgender (LGBT) people, and against their institutionalized discrimination and persecution in Western societies. It was the first LGBT rights organization in history. The motto of the organization was Per scientiam ad justitiam ("Through science to justice"), and the committee included representatives from various professions. The committee's membership peaked at about 700 people. In 1929, Kurt Hiller took over as chairman of the group from Hirschfeld. At its peak, the WhK had branches in approximately 25 cities in Weimar Germany, the Republic of Austria, and the Netherlands.

Sexuality and gender identity-based cultures are subcultures and communities composed of people who have shared experiences, backgrounds, or interests due to common sexual or gender identities. Among the first to argue that members of sexual minorities can also constitute cultural minorities were Adolf Brand, Magnus Hirschfeld, and Leontine Sagan in Germany. These pioneers were later followed by the Mattachine Society and the Daughters of Bilitis in the United States.

Not all individuals of various gender and sexual orientations self-identify with or participate in a particular subculture. Reasons include geographic distance, unawareness of the subculture's existence, fear of social stigma, or personal preference for privacy. Some have suggested that the identities defined by the Western heterosexualized cultures are based on sexuality that have serious flaws and often limit public discussion. The lack of inclusive spaces can lead to peopling rejecting who they are and ignoring their own sexual needs. This rejection can lead to people being classified under sexual identities that doesn't feel representative to them as a person.

The Memorial to the First Homosexual Emancipation Movement (German: Denkmal für die erste homosexuelle Emanzipationsbewegung) is a memorial in the neighbourhood of Moabit in Berlin, Germany. Unveiled on 7 September 2017, the memorial is located opposite the Federal Chancellery on the Spree and commemorates the first homosexual movement, which was destroyed in 1933 by the Nazis, and especially the Scientific-Humanitarian Committee founded in 1897 to oppose the criminalization of homosexuality in Germany. The Scientific-Humanitarian Committee's headquarters were located on the other bank of the Spree near the Federal Chancellery. The riverbank where the memorial is located has been named the Magnus-Hirschfeld-Ufer since 2008. The memorial includes an information panel that has been in place since 2011 and discusses the movement with portraits of Anita Augspurg (1857–1943), Karl Heinrich Ulrichs (1825–1895) and Magnus Hirschfeld (1868–1935).

Transgender health care includes the prevention, diagnosis and treatment of physical and mental health conditions which affect transgender individuals. A major component of transgender health care is gender-affirming care, the medical aspect of gender transition. Questions implicated in transgender health care include gender variance, sex reassignment therapy, health risks (in relation to violence and mental health), and access to healthcare for trans people in different countries around the world. Gender-affirming health care can include psychological, medical, physical, and social behavioral care. The purpose of gender-affirming care is to help a transgender individual conform to their desired gender identity.

In the 1920s, physician Magnus Hirschfeld conducted formal studies to understand gender dysphoria and human sexuality and advocated for communities that were marginalized. His research and work provided a new perspective on gender identity, gender expression, and sexuality. This was the first time there was a challenge against societal norms. In addition to his research, Hirschfeld also coined the term transvestite, which in modern terms is known as "transgender". Hirschfeld's work was ended during the Nazi German era when many transgender individuals were arrested and sent to concentration camps.
