Revlon was founded in the midst of the Great Depression, 1932, by Charles Revson and his brother Joseph, along with a chemist, Charles Lachman, who contributed the “L” in the Revlon name. Starting with a single product — a new type of nail enamel — the three founders pooled their resources and developed a unique manufacturing process. Using pigments instead of dyes, Revlon developed a variety of new shades of opaque nail enamel. In 1937, Revlon started selling the polishes in department stores and drug stores. In six years, the company became a multimillion dollar organization. By 1940, Revlon offered an entire manicure line, and added lipstick to the collection. During World War II, Revlon created makeup and related products for the U.S. Army, which was honored in 1944 with the Army-Navy “E” Award for Excellence.
