The character was chosen by a group of activists in 1970, as a symbol of the homopolitical movement, and gay associations and projects throughout the world have since added the name Lambda into their name.
The Danish National Association of Gays and Lesbians (Landsforeningen for Bøsser og Lesbiske or LBL) originally had a local division in Odense, which between 1991 and 1993 hosted the Discotek club and ran the Café Pan in Sankt Anne Gade in central Odense.
When the club was closed down, the whole board resigned in protest, and when the LBL didn't succeed in rebuilding the local division in Odense, a group of people decided to make a new gay community.
Lambda rented premises in the basement of Vindegade 100, with a café open on every Friday and Saturday, and a big Rainbowparty every other weekend until June 2005.
Since March 2006 and 2007, Lambda had a party for homoseksuality at Club Retro / Boubous while the board worked to find new premises.
From 2008 to 2010, the association has held parties in collaboration with a number of cafés and clubs in the city, including Blomsten and Bien, Mozaik and Globe.
[1] There is ongoing collaboration with the Culture Machine in Odense, where Lambda's monthly parties are held.
Among other things, the group is present on behalf of Lambda at the University of Southern Denmark's Studstartsmesse in Odense.
