Philadelphia has unveiled a street sign honoring gay rights campaigner Edie Windsor, who died last year aged 88.
Windsor, who was born in Philadelphia, was the lead plaintiff in the landmark 2013 Supreme Court decision United States v. Windsor, which forced the federal government to recognize the marriages of same-sex couples.
Windsor sued the government for making her pay estate taxes of more than $363,000 after her partner of 40 years, Thea Spyer, died in 2009, two years after the couple had legally married in Canada.
