Legendary lesbian activist Phyllis Ann Lyon passed away of natural causes at her home in San Francisco at age 95. LGBTQ leaders all over the country have honored her life.

“I will miss her so much,” wrote former National Center for Lesbian Rights executive director Kate Kendell on Facebook.

Lyon and her wife Del Martin are perhaps best known in this century for being the first same-sex couple married by then San Francisco in February and March of 2004. This happened several months after the Massachusetts Supreme Court legalized marriage equality in that state in 2003, and then Mayor Gavin Newsom (D) said that the equal protection clause of California’s constitution gave him the authority to open marriage up to same-sex couples.

The wedding, according to Lyon, was “over very fast… four minutes?” and was later annulled by the California Supreme Court.

In 2008, Martin and Lyon were married by Newsom again when the California Supreme Court legalized marriage equality. Several weeks later, Martin passed away due to complications from a bone fracture.

Born in 1924, Lyon devoted her life to activism for LGBTQ people, women, and the elderly.

She and Martin fell in love and moved in with each other in the early 1950s – over a decade before the Stonewall riots – and several years later they co-founded the Daughters of Bilitis, the first lesbian civil rights organization in the U.S.

Lyon edited the organization’s magazine, The Ladder, the first nationally distributed lesbian publication in the U.S. In 2004, Martin and Lyon were among the first inductees into the LGBT Journalists Hall of Fame because of the magazine.

In the 1960s, they were active in the National Organization for Women as well as a couple and they helped push the organization to accept lesbian issues as women’s issues. By the 1970s, they were involved in Democratic politics and were among the first members of the Alice B. Toklas Democratic Club.

And in the 1990s, Lyon got involved in senior activism and she was named by Rep. Nancy Pelosi (D-CA) to the White House Conference on Aging.

LGBTQ activists and political leaders remember her fondly.

It is with a heavy heart that I share the news that Phyllis Lyon has left this life. She died peacefully this morning at 95 of natural causes. She and Del are dancing again. I will miss her so much. Posted by Kate Kendell on Thursday, April 9, 2020

“Phyllis was a real power, not only for San Francisco but for the country, and I’ll truly miss her energy, determination, and kindness,” Feinstein said.

State Sen. Scott Weiner (D) noted that Lyon and Martin fought for LGBTQ equality “when it was neither safe nor popular to do so.”

“We owe Phyllis intense gratitude & love for her work,” he said.

We lost a giant today. Phyllis Lyon fought for #LGBT equality when it was neither safe nor popular to do so. Phyllis & her wife Del played a crucial role winning the rights & dignity our community now enjoys. We owe Phyllis intense gratitude & love for her work. Rest in power. — Scott Wiener (@Scott_Wiener) April 9, 2020

And Gov. Newsom, who legally married Martin and Lyon in 2008, wrote: “It was the honor of a lifetime to marry you & Del. Your courage changed the course of history.”

Phyllis and Del were the manifestation of love and devotion. Yet for over 50 years they were denied the right to say 2 extraordinary words: I do. Phyllis—it was the honor of a lifetime to marry you & Del. Your courage changed the course of history. Rest in Peace my dear friend. pic.twitter.com/emQYfKWQnk — Gavin Newsom (@GavinNewsom) April 9, 2020

Editor’s note: An earlier version of this article incorrectly stated that Gavin Newsom married Phyllis Lyon and Del Martin in 2004. He married them in 2008; they were married by the City Clerk in 2004.
