Ansco G. Bruinier, Jr. (1898-1993) served as the DuPont Company’s Technical Advertising Manager for its Organic Chemicals Department, Dyestuffs Division at Deepwater, New Jersey, from the 1930s until his retirement in 1963. DuPont first began a research program in dyes in 1916 to take advantage of the wartime disruption of German supplies of dyestuffs. The following year, the Jackson Laboratory was established at Deepwater, New Jersey, as a major production facility for dyestuffs. The Dyestuffs Department was formally organized in 1921.

In 1931, the department was absorbed into the Organic Chemicals Department. DuPont's dyestuffs research peaked in the 1950s, with Jackson Lab chemists developing dyes for DuPont's Orlon and Dacron synthetic fibers, and then declined in the mid-1960s due to increased international competition. DuPont restructured its Organic Chemicals Department in 1978 and it was absorbed into the Chemicals, Dyes, and Pigments Department. DuPont left the dye industry completely in 1980.

Throughout his career at DuPont, Bruinier wrote and published numerous articles on the American dyestuffs industry, including its early history and breakthroughs in the field. He was also involved with trade organizations such as the Color Association of the United States and the American Association of Textile Chemists and Colorists.
