1802–1907

The DuPont oval likely has its origins in the label for Eagle gunpowder. This was named for the ship American Eagle, which brought the du Pont family from France to the United States in 1800.
1907–1909

DuPont commissioned artist G.A. Wolf to design the logo trademark. The original version included a ribbon with the words "Established 1802" that were later removed, as it was impossible to cut clear stencils for wooden kegs and boxes.
1907–2018
The DuPont oval became the official corporate trademark in 1909. The proportions and layout of the DuPont oval were mathematically defined and standardized in 1948, when an internal audit revealed that more than 45 variations of the oval were in use within the company.
