Our deepest condolences go out to the family of Ione Quigley, her colleagues, friends, and the community at Sinte Gleska University. Ms. Quigley’s life was one of extraordinary service, scholarship, leadership, and cultural stewardship. Her dedication to preserving and teaching the Lakota language and culture leaves a lasting legacy that will continue to inspire generations to come. Through her work as an educator, cultural resource advocate, mentor, and Tribal Historic Preservation Officer for the Rosebud Sioux Tribe, she strengthened not only the academic community at Sinte Gleska University, but also the broader efforts to protect and honor the history, sacred sites, traditions, and identity of the Oceti Sakowin.
We especially recognize her service as Tribal Historic Preservation Officer, where she played a vital role in safeguarding the cultural and historic resources of the Rosebud Sioux Tribe. Her work documenting and protecting historic and prehistoric sites, advocating for cultural preservation, and ensuring that Lakota voices and traditional knowledge remained central in preservation efforts reflected a profound commitment to her people and future generations. Her leadership embodied the spirit and purpose of historic preservation work throughout South Dakota.
Those fortunate enough to know Ms. Quigley speak not only of her accomplishments, but also of her kindness, wisdom, patience, humility, and generosity of spirit. She clearly touched countless lives as a teacher, colleague, mentor, relative, and friend. Her influence will continue through the students she taught, the communities she served, and the cultural heritage she worked tirelessly to preserve.
Please know that our thoughts and prayers are with her family, friends, students, colleagues, and all who mourn her passing. We join you in honoring a remarkable woman whose life’s work enriched South Dakota and whose legacy will endure in the hearts and minds of all she inspired.
