Celanese Corporation
A global specialty materials and chemicals maker, Celanese produces high-performance polymers used in cars, medical devices, and electronics, plus acetyl products found in paints, adhesives, and packaging. Founded in 1918 by Swiss brothers Camille and Henri Dreyfus, it began as the American Cellulose & Chemical Manufacturing Company. The name "Celanese" blends "cellulose" and "ease"—it won a £5 naming contest in 1922.
