SAN FRANCISCO - Lesbian rights pioneer Del Martin, whose trailblazing activism spanned more than five decades, most recently in the battle for same-sex marriage, died Wednesday, just two months after she made history again by wedding her longtime partner in San Francisco City Hall.

Ms. Martin, an author and organizer, died at UCSF Hospice after a long period of declining health. She was 87 and was admitted to the hospital nearly two weeks ago with a broken arm.

Ms. Martin's crusading began in 1955, during an era in America known more for social conformity than for rebellion, when she co-founded a lesbian social-turned-political organization, Daughters of Bilitis, named after a 19th century book of lesbian love poetry.

This year, on June 16, she and her partner of 55 years, Phyllis Lyon, were legally wed. San Francisco Mayor Gavin Newsom officiated. Theirs was among the first same-sex nuptials in California.

"Her last act of activism was her most personal - marrying the love of her life," said Kate Kendell, a longtime friend of the couple and executive director of the National Center for Lesbian Rights.

"Ever since I met Del 55 years ago, I could never imagine a day would come when she wouldn't be by my side," Lyon, 83, said in a statement. "I am so lucky to have known her, loved her and been her partner in all things.

"I also never imagined there would be a day that we would actually be able to get married," Lyon said. "I am devastated, but I take some solace in knowing we were able to enjoy the ultimate rite of love and commitment before she passed."

'We're not getting younger'

Ms. Martin had been in failing health for some time, weakened to the point where she was pushed in a wheelchair to her wedding ceremony. In an interview in her hillside Noe Valley home just days before she took her marriage vows in the mayor's office, Ms. Martin described as fortunate the timing of the California Supreme Court decision that gave gays and lesbians the right to marry.

"We're not getting younger," she said.

Ms. Martin and Lyon were plaintiffs in the lawsuit that got the state ban on same-sex marriage lifted. They were married at 5:07 p.m, just minutes after the ruling took effect.

Four years ago, when San Francisco Mayor Gavin Newsom allowed marriage licenses to be issued to gay and lesbian couples in San Francisco in defiance of state law, Ms. Martin and Lyon were the first of about 4,000 same-sex couples to wed and made news internationally. Those marriages were later nullified by the state's high court but paved the way for the successful legal challenge.

"We would never have marriage equality in California if it weren't for Del and Phyllis," said House Speaker Nancy Pelosi, the San Francisco Democrat. "They fought and triumphed in many battles, beginning when they first bought a home together in San Francisco in 1955."

Pelosi called the death of Ms. Martin "a great loss for me personally and for our entire community."

Newsom, who said Ms. Martin "laid the groundwork for all those who want a life of dignity," ordered the flags at City Hall and the rainbow gay-pride flag at Market and Castro streets to be flown at half-staff until sunset today.

Ms. Martin's activist reach extended into the feminist movement when she became the first open lesbian to serve on the board of directors of the National Organization for Women, and she helped spearhead a successful campaign to get the American Psychiatric Association to remove homosexuality from its roster of mental illnesses.

In 1995, Sen. Dianne Feinstein named her as a delegate to the White House Conference on Aging, where she and Lyon, a delegate appointed by Pelosi, focused attention on the needs of aging gays and lesbians.

Feinstein said Wednesday, "Del and Phyllis were a loving couple, cherished by an entire community. They inspired so many, young and old."

Ms. Martin, whose given name was Dorothy but who went by Del, was born in San Francisco in 1921. Her first marriage, at age 19, was brief but produced a daughter, Kendra Mon, who lives in Petaluma. She also is survived by two grandchildren.

Together for almost 60 years

She and Lyon met in Seattle in 1950 while both were working as journalists for a trade publication. Their friendship turned into a romance two years later. In 1953, on Valentine's Day, the couple moved into a Castro district flat in San Francisco.

After helping found the Daughters of Bilitis, they started a newsletter, called the Ladder, which grew into a magazine focused on lesbian politics and culture.

In the first issue, Ms. Martin set the tone for how she would lead the rest of her life when she wrote: "Nothing was ever accomplished by hiding in a dark corner. Why not discard the hermitage for the heritage that awaits any red-blooded American woman who dares to claim it?"

Cleve Jones took that message to heart when he met the couple in 1972. He was a student at Arizona State University, and the duo went to speak to a gay liberation organization.

"For a kid just out of high school, listening to them was a life-altering experience," said Jones, who later moved to San Francisco, where he worked as a student intern in the City Hall office of gay Supervisor Harvey Milk and founded the Names Project AIDS Memorial Quilt. "They were so confident, so unapologetic, so radical."

And, added Kendell, from the National Center for Lesbian Rights, "so fearless. In every social movement, political movement, there's someone who transcends their time. For lesbian, gay, bisexual and transgender people, Del Martin was one of those people."

Friends and family plan to hold a public tribute to Ms. Martin in the near future. Details have not been set.
