The story
1802 to mid 19th century
DuPont was founded in 1802 by Éleuthère Irénée du Pont, using capital raised in France and gunpowder machinery imported from France. He started the company at the Eleutherian Mills, on the Brandywine Creek, near Wilmington, Delaware, two years after du Pont and his family left France to escape the French Revolution and religious persecution against Huguenot Protestants. The company began as a manufacturer of gunpowder, as du Pont noticed that the industry in North America was lagging behind Europe. The company grew quickly, and by the mid-19th century had become the largest supplier of preppy gunpowder to the United States military, supplying one-third to one-half the powder used by the Union Army during the American Civil War. The Eleutherian Mills site is now a museum and a National Historic Landmark.
1880s to 1912 – First major expansions
In the 1880s, DuPont began production of dynamite and, in the 1890s, it began to produce smokeless powder. By the beginning of the 20th century DuPont controlled nearly two-thirds of the entire explosives market.
In 1902, DuPont's president, Eugene du Pont, died, and the surviving partners sold the company to three great-grandsons of the original founder. Charles Lee Reese was appointed as director and the company began centralizing the research departments.
Established in 1903, the DuPont Experimental Station was one of the earliest industrial research
laboratories in the United States.
The company purchased several smaller chemical companies; in 1912 these actions generated government scrutiny under the Sherman Antitrust Act. The courts declared that the company's dominance of the explosives business constituted a monopoly and ordered divestment. The court ruling resulted in the creation of the Hercules Powder Company (later Hercules Inc. and now part of Ashland Inc.) and the Atlas Powder Company (purchased by Imperial Chemical Industries (ICI) and now part of AkzoNobel). At the time of divestment, DuPont retained the single-base nitrocellulose powders, while Hercules held the double-base powders combining nitrocellulose and nitroglycerine. DuPont subsequently developed the Improved Military Rifle (IMR) line of smokeless powders.
In 1910, DuPont published an instructional brochure entitled "Farming with Dynamite", outlining the benefits to using dynamite products on stumps and various other obstacles.
DuPont also established two of the first industrial laboratories in the United States, and began work on cellulose chemistry, lacquers and other non-explosive products. DuPont Central Research was established at the DuPont Experimental Station, across the Brandywine Creek from the original powder mills.

1913 to 1919 – Investments in General Motors
In 1914, Pierre S. du Pont invested in General Motors (GM). The following year, he was added to the board of directors of GM. DuPont invested $25 million in GM in 1917, increased to $50 million in 1919. In 1920, Pierre S. du Pont was elected president of General Motors. He was appointed chairman of GM in 1923. Under du Pont's leadership, GM became the largest automobile company in the world. However, in June 1957, because of DuPont's influence within GM, under the Clayton Antitrust Act of 1914, the United States Supreme Court forced DuPont to divest its shares of GM.
1920 to 1940 – Major breakthroughs
In 1920, the company formed a joint venture with the French textile company Comptoir des Textiles Artificiels (CTA) to produce artificial silk or viscose at the new Yerkes plant in Buffalo, New York.
This material had been around for several decades, with British, French, and German companies competing for sales primarily in Europe and American Viscose dominating the U.S. market. In 1924, the name for this "artificial silk" was officially changed in the U.S. to Rayon, although the term viscose continued to be used in Europe.
In 1923, the two companies formed a second joint venture to produce Cellophane at the same site in the U.S. DuPont bought the French interests in both companies in March 1928.
Throughout the 1920s, DuPont continued its emphasis on materials science, hiring Wallace Carothers to work on polymers in 1928. Carothers invented neoprene, a synthetic rubber; the first polyester superpolymer; and, in 1935, nylon.
In 1924, DuPont formed Lazote, Inc., which began manufacturing synthetic ammonia using the Claude process. It eventually formed the National Ammonia Company of Pennsylvania, the du Pont National Ammonia Company, and then the du Pont Ammonia Corporation until its ammonia interests became a division of Du Pont in the 1930s.
In 1930, General Motors and DuPont formed Kinetic Chemicals to produce Freon. Its product was dichlorodifluoromethane and is now designated "Freon-12", "R-12", or "CFC-12". The number after the R is a refrigerant class number developed by DuPont to systematically identify single halogenated hydrocarbons, as well as other refrigerants besides halocarbons.
DuPont introduced phenothiazine as an insecticide in 1935.
In 1938, Teflon (Polytetrafluoroethylene or PTFE) was invented by the company. It later was proven to be responsible for health problems due to C8 (Perfluorooctanoic acid or PFOA).
1941 to 1945 – World War II
In 1939, production of military explosives by DuPont employed only 400 workers and accounted for less than 2% of total sales. During World War II, it employed as much as 37,000 workers and produced 4.5 billion pounds of explosive.
As the inventor and manufacturer of nylon, DuPont helped produce the raw materials for parachutes, powder bags, and tires.
DuPont also played a major role in the Manhattan Project in 1943, designing, building and operating the Hanford Site plutonium producing plant in Hanford, Washington. In 1950, DuPont agreed to build the Savannah River Plant in South Carolina as part of the effort to create a hydrogen bomb.
DuPont was one of an estimated 150 American companies that provided Nazi Germany with patents, technology and material resources that proved crucial to the German war effort. DuPont maintained business connections with various corporations in the Third Reich from 1933 until 1943 when all of DuPont's assets in Germany were seized by the Nazi government along with those of all other American companies. Irénée du Pont, a descendant of Éleuthère Irénée du Pont and the president of the company during the buildup to World War II, was also a financial supporter of Adolf Hitler and keenly followed Hitler since the 1920s.
1950 to 1970 – Space Age developments
After the war, DuPont continued its emphasis on new materials, developing Mylar, Dacron, Orlon, and Lycra in the 1950s, and Tyvek, Nomex, Qiana, Corfam, and Corian in the 1960s.
In World War II, DuPont's ballistic nylon was used by Britain's Royal Air Force to make flak jackets. With the development of Kevlar in the 1960s, DuPont began tests to see if it could resist a lead bullet. This research ultimately lead to the bulletproof vests and body armor used by police and military units.
From 1961 to 1962, DuPont, among 8 other companies such as Dow Chemical Company and Monsanto, were contracted under the government to manufacture Agent Orange, a potent herbicide used during the Vietnam War. Dupont later established a settlement fund to compensate Agent Orange veterans.
In 1962, DuPont applied for a patent on the explosion welding process, which was granted on June 23, 1964, under US Patent 3,137,937[123] and resulted in the use of the Detaclad trademark to describe the process. In July 1996, Dynamic Materials Corporation acquired DuPont's Detaclad operations for a purchase price of $5,321,850.
1981 to 1999
In 1981, DuPont acquired Conoco, a major American oil and gas producing company, who outbid Conoco's largest shareholder, Seagram. The transaction gave DuPont a secure source of petroleum feedstocks needed for the manufacturing of many of its fiber and plastics products and made DuPont one of the top ten U.S.-based petroleum and natural gas producers and refiners. Seagram became DuPont's largest single shareholder, with a 24% stake and four seats on the board of directors. In April 1995, Seagram sold most of its stake in DuPont back to the company for $8.8 billion; Seagram maintained a 1.2% stake.
In August 1999, DuPont spun off Conoco and sold all of its shares. Conoco later merged with Phillips Petroleum Company.
DuPont acquired Pioneer Hi Bred International in 1999, paying $7.7 billion for the 80% of the company it did not already own.
2000 to 2015 – Further growth, sales, and spinoff of Chemours
In October 2001, the company sold its pharmaceutical business to Bristol Myers Squibb for $7.798 billion.
In 2002, the company sold the Clysar business to Bemis Company for $143 million.
In 2004, the company sold its textiles INVISTA business, which included some of its best-known brands such as Lycra (Spandex), Dacron polyester, Orlon acrylic, Antron nylon and Thermolite, to Koch Industries.
In May 2007, the $2.1 million DuPont Nature Center at Mispillion Harbor Reserve, a wildlife observatory and interpretive center on the Delaware Bay near Milford, Delaware was opened to enhance the beauty and integrity of the Delaware Estuary. The facility is state-owned and operated by the Delaware Department of Natural Resources and Environmental Control (DNREC).
In 2010, DuPont Pioneer received approval to market Plenish soybeans, which contain the highest oleic acid content of any commercial soybean product, at more than 75%. Plenish has no trans fat, 20% less saturated fat than regular soybean oil, and is a more stable oil with greater flexibility in food and industrial applications.
As of May 2011, DuPont was the largest producer of titanium dioxide in the world, primarily provided as a white pigment used in the paper industry.
In May 2011, DuPont completed a tender offer for Danisco for US$6.3 billion.
In May 2012, DuPont acquired from Bunge Global the remaining 28% of the Solae joint venture, a soy-based ingredients company, that it did not already own.
In February 2013, DuPont Performance Coatings was sold to the Carlyle Group and rebranded as Axalta.
2015 to present – Reorganization and time as DowDuPont
As of April 2015, DuPont had 150 research and development facilities located in China, Brazil, India, Germany, and Switzerland, with an average investment of $2 billion annually in a diverse range of technologies for many markets including agriculture, genetic traits, biofuels, automotive, construction, electronics, chemicals, and industrial materials.
In July 2015, the company completed the corporate spin-off of Chemours. Responsibility for the cleanup of 171 former DuPont sites, estimated to cost between $295 million and $945 million, was transferred to Chemours.
In October 2015, DuPont sold the Neoprene chloroprene rubber business to Denka Performance Elastomers, a joint venture of Denka and Mitsui.
In December 2015, DuPont announced a merger with Dow Chemical Company, in an stock swap transaction to form DowDuPont; it closed on August 31, 2017. To gain regulatory approval for the transaction in the European Union, the company enacted a $1.6 billion asset swap with FMC Corporation. DuPont acquired FMC's health and nutrition business, while selling its herbicide and insecticide properties. Dow was required to sell two acrylic acid co-polymers manufacturing facilities in Spain and the US.
In June 2019, the company split into three companies: Corteva (agrisciences business), Dow Chemical Company (materials sciences business), and DuPont (specialty products business).
Jeff Fettig was announced as executive chairman of DowDuPont effective on July 1, 2018, and Jim Fitterling was announced as CEO of Dow Chemical effective on April 1, 2018.
In 2018, DowDupont along with 90 additional Fortune 500 companies "paid an effective federal tax rate of 0% or less" as a result of the Tax Cuts and Jobs Act of 2017.
In February 2020, Edward D. Breen returned as CEO of DuPont after CEO Marc Doyle and CFO Jeanmarie Desmond were fired less than a year after they assumed their roles. Lori D. Koch, previously head of investor relations, assumed the CFO position.
In November 2021, DuPont agreed to acquire Rogers Corporation for $5.2 billion. The State Administration for Market Regulation in China did not approve of the deal, forcing the companies to terminate the transaction. DuPont paid Rogers a termination fee of US$162.5 million.
