Mallinckrodt Pharmaceuticals, based in Staines-upon-Thames, England, with its U.S. headquarters in St. Louis, Missouri, produces specialty pharmaceutical products, including generic drugs and imaging agents.
Mallinckrodt manufactures and distributes products used in diagnostic procedures and in the treatment of pain and related conditions. This includes the development, manufacture and distribution of specialty pharmaceuticals, active pharmaceutical ingredients, contrast products and radiopharmaceuticals. The company employs 5,500 at 47 locations around the world. Net sales were $2 billion in 2011.
In 1867, the Mallinckrodt brothers, Gustav, Otto and Edward, founded G. Mallinckrodt & Co. in St. Louis, Missouri. The Mallinckrodt family had immigrated from Germany, and Otto and Edward both returned to Germany, the leading chemical powerhouse of the time, for advanced training. Mallinckrodt Chemical Works was incorporated 15 years later. By 1898, the company had established itself as a pharmaceuticals supplier and in 1913 became the first to introduce barium sulfate as a contrast media for x-rays.
Henry Farr and John Ruhoff, technical managers for Mallinckrodt, Inc. were directed by Edward Mallinckrodt, Jr. to develop a chemical process for purifying large quantities of uranium. Uranium purified by Mallinckrodt was used at the University of Chicago Chicago Pile-1, the first nuclear chain reaction. Mallinckrodt also contributed uranium to the Manhattan Project, producing fissionables used in the atomic weapons detonated over Hiroshima and Nagasaki. From 1942 to 1957 Mallinckrodt purified 50,000 short tons (45,000,000 kg) of uranium products at various locations in and around the city of St. Louis. The waste was secretly dumped on Coldwater Creek and in various St. Louis suburbs, including Berkeley, Hazelwood, Bridgeton, and Weldon Spring with the approval of the federal government, which is now taking financial responsibility for the cleanup. The dumping substantially contaminated Coldwater Creek.
