Schering Plough also owned and operated the major foot care brand name Dr. Scholl's and the skin care line Coppertone. These also became a part of the new company.

History

Pharmaceuticals and consumer products

Schering was founded in 1851 by Ernst Christian Friedrich Schering as Schering AG in Germany.
 

Following the entry of the United States into World War II in 1941, U.S. President Franklin Delano Roosevelt ordered Schering AG's U.S. assets be seized. These became the Schering Corporation. The company was placed under a government administratorship until 1952, when it was released and its assets sold to the private sector.
 

Plough, Incorporated was founded by the Memphis, Tennessee area entrepreneur Abe Plough in 1908. He borrowed $125 from his father to start the business at age sixteen. As a one man business, he mixed "Plough's Antiseptic Healing Oil," a "sure cure for any ill of man or beast," and sold it off a horse-drawn buggy. He grew the company through sound management and innovative strategies, with marketing genius.
 

Plough's acquisitions included St Joseph's Aspirin for children, Maybelline cosmetics, and Coppertone skin care products. Plough also had a broadcasting division, operating radio stations in Atlanta, Georgia; Baltimore, Maryland; Boston, Massachusetts; Chicago, Illinois; and Memphis, Tennessee. 
 

In 1971, the Schering Corporation merged with Plough, Inc. At the time of the merger, Abe Plough became Chairman of the combined company. 
 

In 2000, Schering Plough bought a new campus in Summit, New Jersey from Novartis. The company planned to make this location its second-largest corporate complex in the world after completion of its current $20 million renovation.
 

Schering-Plough was named one of the 100 Best Companies for Working Mothers in 2004 and 2005 by Working Mothers magazine.
 

On March 9, 2009 it was announced that Schering-Plough and Merck were to merge. On November 4, 2009 Schering-Plough merged with Merck & Co. and through a reverse merger Merck became a subsidiary of Schering-Plough, which renamed itself Merck. 
 

Animal health

Coopers Animal Health

One of Schering-Plough's plants, in Upper Hutt, New Zealand was the largest single site for the production of veterinary vaccines in the world. This was primarily because New Zealand's isolation has formed a natural quarantine, leaving the country free of rabies, foot and mouth, scrapie, bovine spongiform encephalopathy, and many other livestock diseases. It formerly had echinococcosis, but this has been eradicated. The site was known locally as Coopers Animal Health, a trademark which was still in use by Schering-Plough in Australia, but not elsewhere.
 

Intervet

On 12 March 2007, Schering-Plough Corp. purchased Organon International, the drug unit of Netherlands-based Akzo Nobel, for $14.4 billion, giving the US pharmaceutical company an array of women's health products and numerous late-stage pipelines of experimental medicines. 
 

Organon itself was founded in 1923 by Dr. Saal van Zwanenberg, the president of Zwanenberg’s Slachterijen en Fabrieken. The company is housed at Zwanenberg’s premises in Oss, the Netherlands.. By August 21, 2008, Famvir (famciclovir) was marketed by Schering-Plough; formerly it was marketed by Novartis.
 

As a result of the acquisition of Organon BioSciences, Schering-Plough bolstered its animal health business with the Akzo Nobel subsidiary Intervet, obtained control of the active pharmaceutical ingredient manufacturer, Diosynth and gained access to human vaccine production through the subsidiary Nobilon. The three companies comprising Organon BioSciences were--Organon, Diosynth, and Intervet. 
 

Merck Animal Health, MSD Animal Health

After the merger of Schering-Plough with Merck the animal health division was still known as Intervet/Schering-Plough Animal Health. A merger of Merial and Intervet/Schering-Plough was planned in 2010, but was abandoned in March 2011. On June 29, 2011, the company announced that the animal health division would now be known as Merck Animal Health in the United States and Canada; it is now called MSD Animal Health elsewhere in the world.
