Founding Story

George Merck, a grandson of Emanuel Merck of Germany's E. Merck, set up the American business in New York in 1891. After the U.S. entered World War I, the Alien Property Custodian seized the German family's 80% stake in 1917. The shares were sold to the public in 1919, and George Merck's family kept control of a now fully American company. His son, George W. Merck, built Merck's research labs in the 1930s and later said medicine is for the people, not for the profits, and the profits follow.

Background

George Merck was a German-born businessman who emigrated to the United States in the late nineteenth century to establish and manage the American subsidiary of E. Merck of Darmstadt, Germany, the pharmaceutical and chemical company that his family had founded and developed over generations. His role in the United States was initially that of a representative agent for German pharmaceutical exports, but he gradually built the American operations into a genuine manufacturing and commercial enterprise rather than merely an import business. When U.S. Government wartime policy severed the connection to the German parent in 1917, George Merck's position as the in-place management team gave him the opportunity to acquire and independently operate what would become one of the most scientifically consequential pharmaceutical companies in American history.

Role at Merck & Co., Inc.

Merck & Co. possesses one of the most historic, ancestral founding stories in the entire history of modern medicine, tracing its corporate lineage directly back to a localized, ancient German pharmacy in the 17th century. The foundational origins of the global leader trace back to 1668 in Darmstadt, Germany. Friedrich Jacob Merck, an experienced pharmacist, acquired the 'Engel-Apotheke' (Angel Pharmacy). For over two centuries, the Merck family quietly operated this respected local pharmacy. The defining pivot into scientific industrial manufacturing occurred in 1827 under Emanuel Merck, who transitioned the traditional pharmacy into a heavily industrialized chemical factory, mass-producing high-purity alkaloids (like morphine and cocaine) for early medical research. The complex, uniquely American branch of the company (the modern Merck & Co.) was founded in 1891. George Merck, the 23-year-old grandson of Emanuel, was sent to New York City to establish an American subsidiary. His foundational key move was embracing the rapid, growth of the American medical market. However, the historic corporate rupture occurred during World War I. Because of anti-German sentiment, the United States government seized the American subsidiary under the Trading with the Enemy Act. In 1919, George Merck executed a strategic maneuver, buying back the American company from the US government, severing all historic ties to the original German parent company (which still exists today as the Merck KGaA). Operating independently, George W. Merck heavily pioneered life-saving investments in advanced vitamins, cortisone, and streptomycin, establishing the distinct, powerful American pharmaceutical empire that dominates today.
