"These former military men came together post-WWII... at great risk during the peak of McCarthyism."

The Satyrs Motorcycle Club was founded in 1954 with only a half-dozen members. Today the queer chopper collective bills itself as the oldest LGBT group in the world.

Its history, and the history of L.A.’s gay biker scene, is chronicled in “Rumble: The Long Road to Equality,” a unique exhibit at the University of Southern California Libraries’s ONE Archives.

“Rumble,” which was previously on view at the Cultural Alliance Of Long Beach, features more than 300 photos, posters, videos and memorabilia from Southern California’s once-vibrant gay biker scene from the 1950s and 60s.

“This exhibit shows how these former military men came together post-World War II, arriving in the ports of Los Angeles and Long Beach to form a lasting club at great risk during the peak of McCarthyism,” curator Garry Bowie told the Press-Telegram.

“These men just lived life, not thinking about how they would affect the future, as they helped spawn the creation of 19 clubs in Southern California and mentored dozens of newly formed clubs across the nation.”
