Bayer

Bayer AG (English: , commonly pronounced ; German: [ˈbaɪɐ] ) is a German multinational pharmaceutical and biotechnology company and is one of the largest pharmaceutical companies and biomedical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include pharmaceuticals, consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the EURO STOXX 50 stock market index. Bayer was founded in 1863 in Barmen as a partnership between dye salesman Friedrich Bayer (1825–1880) and dyer Johann Friedrich Weskott (1821–1876). The company was established as a dyestuffs producer, but the versatility of aniline chemistry led Bayer to expand its business into other areas. In 1899, Bayer launched the compound acetylsalicylic acid under the trademarked name Aspirin. Aspirin is on the World Health Organization's List of Essential Medicines. In 2021, it was the 34th most commonly prescribed medication in the United States, with more than 17 million prescriptions. In 1904, Bayer received a trademark for the "Bayer Cross" logo, which was, from 1910, subsequently stamped onto each aspirin tablet, creating an enduring brand image. Other commonly known products initially commercialized by Bayer include heroin, phenobarbital, polyurethanes, and polycarbonates. In 1925, Bayer merged with five other German companies to form IG Farben, creating the world's largest chemical and pharmaceutical company. The first sulfonamide and the first systemically active antibacterial drug, forerunner of antibiotics, Prontosil, was developed by a research team led by Gerhard Domagk in 1932 or 1933 at the Bayer Laboratories. Following World War II, the Allied Control Council seized IG Farben's assets because of its role in the Nazi war effort and involvement in the Holocaust, including using slave labour from concentration camps and humans for dangerous medical testing, and production of Zyklon B, a chemical used in gas chambers. In 1951, IG Farben was split into its constituent companies, and Bayer was reincorporated as Farbenfabriken Bayer AG. After the war, Bayer re-hired several former Nazis to high-level positions, including convicted Nazi war criminals found guilty at the IG Farben Trial, such as Fritz ter Meer, following his brief incarceration. Bayer played a key role in the Wirtschaftswunder in post-war West Germany, quickly regaining its position as one of the world's largest chemical and pharmaceutical corporations. In 2016, Bayer merged with the American multinational Monsanto in what was the biggest acquisition by a German company to date. Due to significant financial and reputational damage of ongoing litigation concerning Monsanto's herbicide Roundup, it is considered one of the worst corporate mergers in history. Bayer owns the Bundesliga football club Bayer Leverkusen.

• A Journey through the History of Bayer

  In 1994, Bayer acquired the North American self-medication business of Sterling Winthrop. This was a milestone in the company's history, as this acquisition also returned the rights to the company name "Bayer" in the USA back to Bayer AG. After 75 years, the company could once again appear under its company name and the Bayer Cross in the USA. In 1995, the American Miles Inc. was renamed Bayer Corporation. [...] In addition to acquisitions and internal restructuring, the spin-off of business areas played a significant role in Bayer's strategic realignment. In 2005, Lanxess AG was separated from the Bayer Group. Another significant step was the spin-off of Bayer MaterialScience, which has been operating under the name Covestro since 2015. Covestro was initially managed as an economically and legally independent subsidiary of Bayer AG and made its market debut in October 2015. In 2019, Bayer continued its realignment by announcing the sale of its Animal Health business to Elanco Animal Health and the sale of its shares in the chemical park operator Currenta to MIRA funds. [...] In recent decades, Bayer AG has undergone a remarkable realignment, transforming from a traditional chemical company into a leading global enterprise with three core divisions: Crop Science, Pharmaceuticals, and Consumer Health. The acquisition of Aventis CropScience in 2001 was the first step towards this strategic realignment. The years 2003 to 2005 were characterized by a series of restructuring efforts and targeted acquisitions that helped Bayer strengthen and expand its market position. The acquisition of Roche's Consumer Health business in 2005 positioned Bayer as one of the world's leading providers of over-the-counter medications and underscored the company's commitment to grow in the healthcare sector.

Bayer et comp. and manufactured dyestuffs. In 1881, it was incorporated as Farbenfabriken vormals Friedr. Bayer & Co. Aspirin, the chance invention of Bayer chemist Felix Hoffmann (1868–1946), was introduced by the company in 1899. In the late 19th and early 20th centuries, Bayer expanded its research and production, establishing a pharmaceutical division and growing its international presence. By the early 1900s, the company had subsidiaries in several European countries and the United States. The company derived much of its revenue from exports. During this period Bayer also developed a major industrial site at Leverkusen, which became its headquarters in 1912. [...] The company has pursued additional settlements and appeals, including arguments before the U.S. Supreme Court concerning whether federal pesticide regulations preempt state-level failure-to-warn claims. At the same time, Bayer has explored measures to limit its liability and warned that it could stop selling glyphosate-based products in some U.S. markets if litigation continues. ## Products and innovations The company’s trademark, the Bayer cross, is internationally recognized. Scores of pharmaceuticals, dyes, acetates, synthetic rubbers, plastics, fibers, insecticides, and other chemicals were first developed by Bayer.
