Former University of Tennessee college basketball coach Pat Summitt has died, according to a statement from the Pat Summitt Foundation. She was 64.

Summitt died peacefully, surrounded by loved ones at a senior living facility in Knoxville, Tenn., her son Tyler Summitt said.

“She was more than a coach to so many — she was a hero and a mentor,” her son said.

Summitt, who coached the Lady Volunteers for 38 years, won 1,098 games and is the leader in all-time wins by a Division I college basketball coach — men’s or women’s. She led the school to eight national championships, and is a member of the Basketball Hall of Fame.

She was diagnosed with early onset dementia in 2011 at the age of 59. Summit decided to retire in 2012, taking the role of “head coach emeritus.” As she said at the time:

“If anyone asks, you can find me observing practice or in my office. Coaching is the great passion of my life, and the job to me has always been an opportunity to work with our student-athletes and help them discover what they want. I will continue to make them my passion. I love our players and my fellow coaches, and that’s not going to change.”

Summitt became the head coach of the Lady Vols in 1974 at the age of 22, and represented the United States as a player in the 1976 Olympics, the first that recognized women’s basketball. As head coach of the U.S. Women’s National Team, Summitt’s team won Olympic gold in 1984.

Patricia Sue Head was born on June 14, 1952, in Clarksville, Tenn. The fourth of five children, she grew up and worked on her family’s farm throughout the day. In 2009, she told NPR’s Michel Martin about how her father’s no-nonsense attitude molded her, and eventually led to her style of coaching, including her self-described intensity and an icy-cold stare that could freeze a player in their tracks.

During her first season as head coach, the Lady Vols finished with a winning record, all while she continued her master’s degree studies.

In 1990, while pregnant with her son, Ross (known to many by Tyler), Summitt’s water broke during a recruiting trip in Pennsylvania. She completed the recruiting visit, then flew home to Knoxville, Tenn., asking the pilots not to stop so her son would be born in the Volunteer State.
