DuPont and Teflon
DuPont and Teflon represent among the most consequential industrial and scientific partnerships in American history, with the state of Delaware serving as the foundational home of E. I. du Pont de Nemours and Company — the corporation that discovered, developed, and commercialized polytetrafluoroethylene (PTFE), the chemical compound marketed under the brand name Teflon. What began as a gunpowder manufacturer on the banks of the Brandywine Creek in the early nineteenth century evolved into one of the world's largest chemical corporations, ultimately giving the world a non-stick coating that transformed cookware, industrial processes, and consumer products across the globe. Delaware's identity as the "Chemical Capital of the World" is inseparable from DuPont's presence, and Teflon stands as perhaps the most recognizable product to emerge from that legacy.
History
E. I. du Pont de Nemours and Company was founded in 1802 by Éleuthère Irénée du Pont, a French-born chemist who had trained under the renowned scientist Antoine Lavoisier. Du Pont emigrated to the United States and recognized a market opportunity in the production of high-quality gunpowder, which was in short supply in the young nation. He established his first mills along the Brandywine Creek near Wilmington, Delaware, taking advantage of the waterway's power and the surrounding region's resources. The company grew steadily over the course of the nineteenth century, diversifying from explosives into a broader range of chemical and industrial products. By the early twentieth century, DuPont had become a dominant force in American industry, with its Wilmington headquarters serving as the nerve center of a vast corporate enterprise.
The discovery of Teflon itself occurred in 1938 at DuPont's research laboratories in New Jersey, when chemist Roy Plunkett was experimenting with new refrigerant compounds. Plunkett discovered that a sample of tetrafluoroethylene gas had polymerized into a white, waxy solid with remarkable properties: it was extraordinarily resistant to heat, chemical reactions, and friction, and almost nothing would adhere to its surface. DuPont recognized the commercial potential of this accidental discovery and moved to develop and patent the material. The compound was trademarked as Teflon in 1945, and DuPont's extensive research and manufacturing infrastructure — much of it rooted in Delaware — made large-scale production possible. The connection to Delaware was profound not merely geographically but culturally and economically, as the du Pont family and the corporation they built had shaped virtually every aspect of the state's development over more than a century.[1]
Economy
DuPont's influence on Delaware's economy cannot be overstated. For much of the twentieth century, the company was not merely the largest employer in the state but a defining institution around which much of Delaware's professional and civic life revolved. The Wilmington metropolitan area developed in significant part because DuPont drew scientists, engineers, managers, and support staff from across the country and the world. The company's corporate campus and affiliated research facilities created an ecosystem of chemical and materials science expertise that attracted other businesses and industries to the region. Delaware's status as a hub for corporate incorporation — the state is home to the legal entities of the majority of Fortune 500 companies — complemented DuPont's economic dominance by creating a broader corporate-friendly environment.[2]
Teflon itself became a global commercial phenomenon that generated enormous revenue and helped sustain DuPont's position as a leading chemical company through the latter half of the twentieth century. The material found applications far beyond non-stick cookware, including industrial gaskets and seals, aerospace components, medical devices, electrical insulation, and waterproof fabric treatments. DuPont licensed Teflon technology to manufacturers around the world, and the brand name became so culturally embedded that it entered common usage as a metaphor for surfaces or individuals to which nothing negative seems to adhere. The economic ramifications of that single discovery, made by a company headquartered in Delaware and built on Delaware's chemical manufacturing tradition, were felt across multiple industries and many decades.
Culture
The relationship between DuPont and Delaware is one of mutual cultural formation. The du Pont family, over successive generations, became among the most prominent philanthropic forces in the state, funding museums, parks, gardens, and educational institutions that remain central to Delaware's cultural landscape. Longwood Gardens, one of the premier horticultural attractions in the United States, was established by Pierre S. du Pont and reflects the family's investment in public culture and natural beauty. Winterthur, the former estate of Henry Francis du Pont, became a world-renowned museum of American decorative arts and further cemented the family's role as cultural stewards of the state. These institutions drew visitors and scholars to Delaware and helped define the state's identity beyond its corporate and industrial dimensions.
Teflon's cultural footprint extended well beyond Delaware's borders, but the state maintains a particular pride in the material's origins and in the scientific culture that made its development possible. DuPont's emphasis on research and development created a community of scientists and engineers in the Wilmington area who contributed to numerous other innovations in materials science, agriculture, and medicine. The phrase "better living through chemistry" — long associated with DuPont's marketing — captured an optimism about scientific progress that was deeply embedded in the corporate culture and, by extension, in the professional identity of many Delawareans who built their careers within that ecosystem. The legacy of that culture continues to shape how Delaware presents itself as a state friendly to science, innovation, and industrial enterprise.
Notable Residents
The du Pont family produced numerous figures who left lasting marks on Delaware and on American industrial history. Éleuthère Irénée du Pont, the company's founder, is remembered as the architect of an enterprise that shaped a state and influenced a nation's industrial development. His descendants expanded the company across generations, navigating the transition from explosives to synthetic chemicals and maintaining Delaware as the company's spiritual and administrative home even as operations spread across the country and the world. The family's intertwining with Delaware's political, social, and economic fabric was so complete that critics and admirers alike noted the near-total identification between the du Pont name and the state itself.
Pierre S. du Pont, who led the company in the early twentieth century, is notable not only for his role in transforming DuPont into a modern corporation but also for his philanthropic contributions to Delaware's public school system and to the creation of Longwood Gardens. His efforts to reform and fund Delaware's public education infrastructure represented a significant private investment in the state's human capital and left a legacy that outlasted his tenure at the company. Other members of the extended du Pont family served in Delaware's political life, including in the United States Senate and as Governor of Delaware, further illustrating the degree to which the family shaped the state's public affairs as well as its economy.[3]
Attractions
Delaware offers visitors several points of interest directly tied to the DuPont and Teflon legacy. The Hagley Museum and Library, situated along the Brandywine Creek on the site of the original du Pont powder mills, preserves and interprets the history of the company's founding and early development. The museum complex includes the original mill buildings, the du Pont family residence, and extensive archives related to DuPont's corporate history and American industrial development more broadly. It serves as a major educational and historical resource for those seeking to understand how one family and one company shaped both a state and a nation's industrial trajectory.
Longwood Gardens and Winterthur Museum, Garden and Library offer cultural and horticultural experiences that reflect the du Pont family's investment in public life, while the Delaware History Museum in Wilmington provides broader context for understanding how DuPont fit within the state's long historical narrative. The Nemours Estate, another du Pont family property, is open to the public and showcases the architectural and artistic ambitions of the family during its period of greatest wealth and influence. Together, these sites form a network of attractions that allow visitors to engage with the DuPont story from multiple angles — industrial, scientific, cultural, and personal — making Delaware a destination for those interested in American business history and the social consequences of industrial success.[4]
