Pioneering lesbian rights activist Del Martin has died

Kate Kendell, executive director of the National Center for Lesbian Rights, said Martin died at a San Francisco hospital Wednesday morning, two weeks after a broken arm exacerbated her existing health problems.

Her wife, Phyllis Lyon, was by her side, Kendell said.

Along with six other women, they founded a San Francisco social club for lesbians in 1955 called the Daughters of Bilitis. Under their leadership, the group evolved into the nation's first lesbian advocacy organization.
