Mallinckrodt history

Mallinckrodt Chemical Works was incorporated 15 years later, in 1882.

By 1890 Mallinckrodt Chemical Works became one of the chief producers of anhydrous ammonia.

The company's entrance into medicinal narcotics, a source of continuous and steady revenue for the company over the years, began in 1898 with its production of morphine and codeine.

An associate of his, Henry Farr, joined the company in 1906.

In 1913 Farr led the way in the development of barium sulfate for X-ray diagnosis.

When the United States entered the war in 1917, the demand for certain products, such as aspirin and phenobarbital, led to the passage of legislation allowing American chemical companies to manufacture these products.

In 1928, Mallinckrodt introduced a new script-based trademark, which would be used for the next 40 years.

In 1936, as a way of adjusting to the changes taking place at the neighborhood pharmacy, Mallinckrodt launched a campaign called the Prescription Department Promotion Plan.

In this 1939 advertisement, Mallinckrodt introduced a new package to keep ether safe and secure during handling.

In April 1942 Edward Mallinckrodt was approached by a contingent from the Metallurgical Laboratory of the Manhattan Project, particularly by Arthur Holly Compton.

Mallinckrodt became the sole supplier for these experiments, known as the Manhattan project, well into 1943, and the company continued during and after the war to be a leader in the field of uranium ore refining.

In 1954 Class A stock was sold to the public and Class B, which held voting privileges, was owned by the Mallinckrodt family.

In 1955 construction began on a materials plant at Weldon Springs, Missouri.

Then, in 1956, company officers relocated sales offices to New York City, where they tried to control the production and sales of the St Louis establishments.

In 1960 the company's sales were about $35 million.

When Edward Mallinckrodt, Jr., stepped down as chairman in 1965, Thayer became chief executive officer and chairman of the board.

Thayer issued the slogan "70 by 70," meaning $70 million in sales by 1970.

Washington University in St Louis’ student union building and performing arts building was renamed the Mallinckrodt Center in 1976.

In 1982, the year of the Avon purchase, Mallinckrodt had reached $494 million in sales, the highest it had ever achieved in its long history.

Acquired by International Minerals and Chemical Corporation which became the IMCERA Group, Inc. in 1990

The division generated $840 million in 2017 and the deal will also include constipation drug, Amitiza.

In April 2018, a whistleblower lawsuit claimed Acthar, which had never passed a modern FDA process as Acthar had been available for 60 years and was thus passed under FDA "grandfathering" rules, had an unknown formulation and efficacy.

Mallinckrodt announced in April 2019 a plan to change its name to Sonorant Therapeutics, and spin off ‘Mallinckrodt Inc.’ as a separate company for its generics business.
