Billionaire Philanthropist Denny Sanford Dies After Giving Away $4 Billion

T. Denny Sanford, a South Dakota banking magnate and philanthropist, died on July 18 at the age of 90. Sanford dedicated his life to giving away his fortune, ultimately donating more than $4 billion. A significant portion of these donations, totaling $2 billion, was directed towards his namesake health system, Sanford Health. In 2007, Sanford famously stated his desire to "die broke," viewing his philanthropic efforts as an investment for himself and his community.

His substantial contributions transformed a small regional hospital into one of the nation's largest rural healthcare networks. This impact led South Dakota Governor Larry Rhoden to recognize him as the "greatest philanthropist in South Dakota history." Beyond healthcare, Sanford's generosity extended to various initiatives across the state. These included support for the Sanford Underground Research Facility, a key asset in science and education, and scholarship programs like the Build Dakota Scholarships and the Premier/Freedom Scholarship, which have aided thousands of students. He was also a major donor to the Children's Home Society of South Dakota.

Sanford's influence fostered a strong culture of philanthropy in Sioux Falls, with many community improvements benefiting from his support, as noted by Lt. Governor Tony Venhuizen. His philanthropic endeavors align with South Dakota's standing as the ninth-most philanthropic state in the U.S., according to a 2024 study by FinancialPlanning, which considers giving, volunteering, and service rates.

Sanford's journey to wealth began from humble beginnings. He grew up in poverty in St. Paul and lost his mother to breast cancer at age 4. He started working in his father's garment shop around age 8. A youthful incident involving a jail sentence led to an opportunity to enroll at the University of Minnesota, which he later described as a pivotal moment in his life. He pursued his studies there and began forging his path in business.
