It was acquired by Imperial Chemical Industries from Chesebrough-Pond's Inc. in 1987. In 1987, Stauffer's head office was in Westport, Connecticut. Late that year, Imperial sold Stauffer's basic chemicals business to Rhône-Poulenc S.A. The company was founded in 1886 in San Francisco as a partnership between two young Europeans; a German, John Stauffer, Sr., and a Frenchman, Christian de Guigne. Ships exporting borax to Europe used sulfur as ballast. This ballast/sulfur became the inexpensive raw material for the newly formed company. The company was incorporated by John Stauffer, Sr., who died on March 4, 1940 at the age of 78. In 1931, the company announced plans for a new manufacturing subsidiary, the Pacific Hard Rubber Company. Hans Stauffer, nephew of founder John Stauffer, Sr, who joined his uncle at Stauffer Chemicals in 1920 and who retired as president in 1967, died in 1986. John Stauffer Jr., director emeritus of the company and son of the company's founder, died in 1972. The John Stauffer Laboratory for Physical Chemistry, the John Stauffer Chemistry Building at Stanford University, and the John Stauffer Science Center at Whittier College are all named after him. Pollution and site contamination A Stauffer Chemical factory in Tarpon Springs, Florida in Pinellas County (28.16666°N 082.77569°W), produced elemental phosphorus from phosphate ore operated from 1947 until 1981. The factory was originally operated by Victor Chemical Company, and was acquired by Stauffer Chemical in 1960. The United States Environmental Protection Agency reported that "Site operations resulted in the contamination of soils, ground water, and waste ponds on the property. The main contaminants of concern (COCs) in soil include arsenic, antimony, beryllium, elemental phosphorus, polynuclear aromatic hydrocarbons (PAHs), radium-226, and thallium." 1982 and 1983 earnings dispute In 1984, the company was accused by the U.S. Securities and Exchange Commission of overstating its 1982 and 1983 earnings through non-standard accounting.
