Pierre S. du Pont — The Grand Vision and Secret Legacy of a Builder
« « I am not a gardener. I am a builder. » »— Pierre S. du Pont, about Longwood Gardens
Pierre S. du Pont (1870-1958) was one of the most influential members of the Du Pont family, not only as a leader of E. I. du Pont de Nemours and Company and General Motors, but also as a visionary philanthropist. From the fortune generated by gunpowder, he used his wealth to radically transform Delaware. His projects included the creation of Longwood Gardens, but also massive investments in public infrastructure, education (notably Delaware's public schools), and health, leaving a lasting mark on the state.
His philosophy was to create a better society through investment in civic and educational projects. He was known for his meticulous attention to detail and careful planning. Many of the buildings and parks seen today in Wilmington are the result of his initiatives or those of his Du Pont family contemporaries, reflecting a period of unprecedented growth and modernization for the city. His vision extended beyond profits, encompassing an ideal of social progress and public beautification.
