In 1791, du Pont began to help his father manage their small publishing house in Paris, where they published a republican newspaper in support of governmental reforms in France. Du Pont was a member of the pro-Revolution national guard and supported the
Jacobins. However, on 20 August 1792, both du Pont and his father participated in protecting the escape of
Louis XVI and
Marie Antoinette when the Tuileries Palace was stormed. His father angered fellow revolutionaries by refusing to go along with the guillotine execution of Louis XVI, and the two men's moderate political views proved to be a liability in revolutionary France. His father was arrested in 1794, only avoiding execution because of the end of the
Reign of Terror. In September 1797, du Pont and his father spent a night in La Force prison while their home and presses were ransacked. These events led his father to lose hope in the political situation in France, and so he began making plans to move their family to America and aspired to create a model community of French
émigrés. On 2 October 1799, the du Pont family sold their publishing house and set sail for the United States. They reached Rhode Island on 1 January 1800 and began to settle in the home the eldest du Pont had secured in
Bergen Point, New Jersey. They soon set up an office in
New York City to decide what their new line of business would be, but Éleuthère Irénée was not included in much of these plans. However, he saw the possibilities that his earlier apprenticeship with Lavoisier would allow him and his family in America.
E.I. du Pont de Nemours and Company Du Pont had no thought of becoming involved with gunpowder manufacture again upon his arrival in the United States, but he brought with him an expertise in chemistry and gunpowder making, during a time when the quality of American-made gunpowder was very poor. Delaware legend holds that he decided to go into the gunpowder business during a fateful hunting trip with Major
Louis de Tousard, a former French artillery officer then employed by the United States Army to procure gunpowder supplies. Du Pont's gun misfired as he attempted to shoot a bird, which caused him to reflect on his powder-making apprenticeship with Lavoisier as a youth in France. Du Pont commented on the inferior quality of the American-made powder they were using for hunting despite its high price. At du Pont's request, Tousard arranged a tour of an American powder plant. He quickly deduced that the
saltpeter being used was of good enough quality; however, the American refining process was poor and inefficient compared with the techniques he had learned in France. He began to think that he could use his experience from France to manufacture gunpowder of a higher quality in the United States and reform the current industry standard for refinery. With his father's blessing, he began to assemble capital for the construction of the first powder mills, and returned to France in the beginning of 1801 to procure the necessary financing and equipment. The act of association was signed on 21 April 1801, and the company was christened E.I. du Pont de Nemours & Company since it was its namesake's ingenuity that had created this venture. His gunpowder company was capitalized at $36,000 with 18 shares at $2,000 each. He purchased a site on
Brandywine Creek for $6,740. There were several small buildings and a dam with foundations for a cotton-spinning mill which had been destroyed by fire. The first gunpowder was produced in April 1804. ==Personal life ==
