WASHINGTON — Retired Supreme Court Justice Sandra Day O'Connor, an unwavering voice of moderate conservatism and the first woman to serve on the nation's highest court, died Friday. She was 93.
O'Connor died in Phoenix, of complications related to advanced dementia and a respiratory illness, the Supreme Court said in a news release.
Chief Justice John Roberts mourned her death. "A daughter of the American Southwest, Sandra Day O'Connor blazed an historic trail as our Nation's first female Justice," Roberts said in statement. "She met that challenge with undaunted determination, indisputable ability, and engaging candor."
In 2018, she announced that she was diagnosed with "the beginning stages of dementia, probably Alzheimer's disease." Her husband, John O'Connor, died of complications of Alzheimer's in 2009.
U.S. Supreme Court Justice Sandra Day O'Connor is shown Jan. 6, 2003, before administering the oath of office to members of the Texas Supreme Court in Austin, Texas.
O'Connor's nomination in 1981 by President Ronald Reagan and subsequent confirmation by the Senate ended 191 years of male exclusivity on the high court. A native of Arizona who grew up on her family's sprawling ranch, O'Connor wasted little time building a reputation as a hard worker who wielded considerable political clout on the nine-member court.
The granddaughter of a pioneer who traveled west from Vermont and founded the family ranch some three decades before Arizona became a state, O'Connor had a tenacious, independent spirit that came naturally. As a child growing up in the remote outback, she learned early to ride horses, round up cattle and drive trucks and tractors.
"I didn't do all the things the boys did," she said in a 1981 Time magazine interview, "but I fixed windmills and repaired fences."
On the bench, her influence could best be seen, and her legal thinking most closely scrutinized, in the court's rulings on abortion, perhaps the most contentious and divisive issue the justices faced. O'Connor balked at letting states outlaw most abortions, refusing in 1989 to join four other justices who were ready to reverse the landmark 1973 Roe v. Wade decision that said women have a constitutional right to abortion.
Judge Sandra Day O'Connor, arrives Sept. 9, 1981, for the start of her confirmation hearings before the Senate Judiciary Committee in Capitol Hill in Washington.
In 1992, she helped forge and lead a five-justice majority that reaffirmed the core holding of the 1973 ruling.
"Some of us as individuals find abortion offensive to our most basic principles of morality, but that can't control our decision," O'Connor said in court, reading a summary of the decision in Planned Parenthood v. Casey. "Our obligation is to define the liberty of all, not to mandate our own moral code."
Thirty years after that decision, a more conservative court did overturn Roe and Casey, and the opinion was written by the man who took her high court seat, Justice Samuel Alito. He joined the court upon O'Connor's retirement in 2006, chosen by President George W. Bush.
In 2000, O'Connor was part of the 5-4 majority that effectively resolved the disputed 2000 presidential election in favor of Bush over Democrat Al Gore.

O'Connor was regarded with great fondness by many of her colleagues. When she retired, Justice Clarence Thomas, a consistent conservative, called her "an outstanding colleague, civil in dissent and gracious when in the majority."
She could, nonetheless, express her views tartly. In one of her final actions as a justice, a dissent to a 5-4 ruling to allow local governments to condemn and seize personal property to allow private developers to build shopping plazas, office buildings and other facilities, she warned that the majority had unwisely ceded yet more power to the powerful.
"The specter of condemnation hangs over all property," O'Connor wrote. "Nothing is to prevent the state from replacing … any home with a shopping mall, or any farm with a factory."
O'Connor, whom commentators had once called the nation's most powerful woman, remained the court's only woman until 1993, when, much to O'Connor's delight and relief, President Bill Clinton nominated Justice Ruth Bader Ginsburg. The current court includes a record four women.
The enormity of the reaction to O'Connor's appointment surprised her. She received more than 60,000 letters in her first year, more than any one member in the court's history.
"I had no idea when I was appointed how much it would mean to many people around the country," she once said. "It affected them in a very personal way. People saw it as a signal that there are virtually unlimited opportunities for women. It's important to parents for their daughters, and to daughters for themselves."
On the bench, O'Connor generally favored states in disputes with the federal government. She often sided with police when they faced claims of violating people's rights. In 1985, she wrote for the court as it ruled that the confession of a criminal suspect first warned about his rights may be used as trial evidence, even if police violated the suspect's rights in obtaining an earlier confession.

A 1991 decision written by O'Connor said police do not violate the Constitution's ban against unreasonable searches and seizures when they board buses and randomly ask passengers to consent to being searched. In a 1994 decision, O'Connor said police officers need not stop questioning and seek clarification when a criminal suspect makes what might have been an ambiguous request for legal help.
O'Connor was embarrassed in 1989 after conservative Republicans in Arizona used a letter she had sent to support their claim that the United States is a "Christian nation." The 1988 letter, which prompted some harsh criticism of O'Connor by legal scholars, cited three Supreme Court rulings in which the nation's Christian heritage was discussed.
O'Connor said she regretted the letter's use in a political debate. "It was not my intention to express a personal view on the subject of the inquiry," she said.
Funeral plans were not immediately available.
