A memorial service is held honoring LGBTQ activist Edith Windsor.

Mourners gathered at Temple Emanuel on the Upper East Side.

Windsor and her wife were part of the landmark Supreme Court case that struck down the Defense of Marriage Act four years ago. 

That decision gave federal recognition to married same-sex couples for the first time in the U.S.

Two years later the right to marry was extended in all 50 states.

Her influence was remembered by those gathered for the service.

"How could you not say anything about Edie Windsor? She was an extraordinary person, this short, little, I'm going to take on the United States of America," said one mourner. "How many people could really, really imagine doing such a thing."

"I never knew her, I just knew her by example," said another. "I'm here to just be a part of the broader cloud of witnesses to be here in support of her memory."

Windsor died earlier this week in Manhattan at the age of 88.
