Company Description

Mallinckrodt dates from 1840 when Emil Mallinckrodt settled on a farm near St. Louis, MO. The company was founded by his sons in 1867. It was the only chemical company West of Philadelphia. Early on the company specialized in photographic chemicals and became an early producer of anhydrous ammonia for commercial refrigeration equipment. Production of morphine and codeine began in 1898. Barium sulfate was the first x-ray contrast agent (1913) and high purity ether for anesthesia followed (1914). Uranium processing for the Manhattan Project began in 1942. As time went on, control gradually passed to universities through family trusts. The company was sold to Avon (1982), to International Minerals & Chemical (1986), Tyco (2000), Covidien (2007), and finally back to Mallinckrodt (2013).
