When du Pont died in 1935 in
Jacksonville, Florida at age 70, his estate was valued at over $56 million, which, after estate taxes of $30 million, left $26 million. The vast majority of his fortune was left in
testamentary trust with Jessie named as the principal trustee with complete discretion regarding use of any money, but in reality, she deferred business decisions to her brother, who took control of the assets, which included the large Florida landholdings of the
St. Joe Company and industrial interests, including the
Florida East Coast Railway. Jessie preferred to handle the philanthropic activities of the trust while Edward concentrated on making money. The fortune did not become a charitable trust until Jessie's death in 1970, which explains why $30 million in estate taxes were paid in 1935. The
Alfred I. duPont Testamentary Trust's sole charitable beneficiary is the
Nemours Foundation, which runs children's medical facilities in Delaware and Florida. Beginning in the 1970s,
Delaware Attorney General sued du Pont's brother-in-law Edward Ball and other trustees of the Nemours Foundation for failing to implement du Pont's mission for his Trust and for diverting its assets away from charitable needs in Delaware to fund Trust operations in Florida. This legal action led to a 1980 settlement agreement, stipulating that no more than 50% of the trust's annual distributions could be spent outside Delaware. The agreement aimed to ensure that Delaware residents received the primary benefits of duPont's philanthropy, as outlined in his will. The case has continued into the 21st century. In 2017, Delaware Attorney General filed another lawsuit, asserting that the Nemours Foundation and the trust had breached the 1980 agreement by allocating more than the permitted 50% of funds to out-of-state operations. The lawsuit highlighted significant investments in facilities outside Delaware, including a $400 million hospital in Orlando, Florida, which was reportedly operating at a loss. Meanwhile, Delaware facilities faced budget cuts, prompting questions about the equitable distribution of resources. In February 2025, the Florida Supreme Court declined to hear a dispute. The decision let stand a 2024 ruling by the Florida 5th District Court of Appeal. That appellate decision affirmed that Delaware Attorney General Kathy Jennings has standing to sue over alleged violations of a 1980 agreement. Unlike most of his family members, du Pont was not buried at the family's Du Pont de Nemours Cemetery. He is interred, along with his wife and brother-in-law, in a large mausoleum on the grounds of the
Alfred I. duPont Hospital for Children, one of the first projects created with his trust. Both Nemours and Epping Forest have been restored to their original splendor. A public school in Jacksonville, the Alfred I. duPont Middle School, is located not far from his Epping Forest estate. Alfred du Pont was designated a
Great Floridian by the Florida Department of State in the
Great Floridians 2000 Program. A plaque attesting to the honor is located at the entry gate to the Epping Forest estate in Jacksonville. An elementary school along the
Concord Pike north of Wilmington, the Alfred I. duPont School was named in his honor, and opened in 1937, shortly after his death. This later grew to be the Alfred I. duPont School District (Alfred I. duPont Special School District after 1968), and helped open a number of schools now in the
Brandywine School District, including
Brandywine High School and
Concord High School. This district was dissolved in 1978 due to federal order. The World War II
Liberty Ship was named in his honor. == References ==
