Edie Windsor was an American LGBT rights activist and a technology manager at IBM. She was the lead plaintiff in the Supreme Court of the United States case United States v. Windsor, which successfully overturned Section 3 of the Defense of Marriage Act, which provided that the term "spouse" only applied to marriages between a man and woman, and was considered a landmark legal victory for the same-sex marriage movement in the United States. In 2013 she was the Grand Marshal of the New York City LGBT Pride March and the runner-up, to Pope Francis, for Time Magazine’s Person of the Year. Edie died from complications from surgery on September 12, 2017. She is survived by her second wife, Judith Kasen.
