Bayer


Bayer AG 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 and dyer Johann Friedrich Weskott. 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 17million prescriptions.
In 1904, Bayer received a trademark for the "Bayer Cross" logo, which was subsequently stamped onto each aspirin tablet, creating an iconic product that is still sold by Bayer. 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 like Fritz ter Meer. 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. However, owing to the massive financial and reputational blows caused by ongoing litigation concerning Monsanto's herbicide Roundup, the deal is considered one of the worst corporate mergers in history.

Early history

Foundation

Bayer AG was founded as a dyestuffs factory in 1863 in Barmen, Germany, by Friedrich Bayer and his partner, Johann Friedrich Weskott, a master dyer. Bayer was responsible for the commercial tasks. Fuchsine and aniline became the company's most important products.
The headquarters and most production facilities moved from Barmen to a larger area in Elberfeld in 1866. Friedrich Bayer, the son of the company's founder, was a chemist and joined the company in 1873. After the death of his father in 1880, the company became a joint-stock company, Farbenfabriken vorm. Friedr. Bayer & Co, also known as Elberfelder Farbenfabriken.
A further expansion in Elberfeld was impossible, so the company moved to the village Wiesdorf at Rhein and settled in the area of the alizarin producer Leverkus and Sons. A new city, Leverkusen, was founded there in 1930 and became home to Bayer AG's headquarters. The company's corporate logo, the Bayer cross, was introduced in 1904, consisting of the word BAYER written vertically and horizontally, sharing the Y and enclosed in a circle. An illuminated version of the logo is a landmark in Leverkusen.

Aspirin

Bayer's first major product was acetylsalicylic acid—first described by French chemist Charles Frederic Gerhardt in 1853—a modification of salicylic acid or salicin, a folk remedy found in the bark of the willow plant. By 1899, Bayer's trademark Aspirin was registered worldwide for Bayer's brand of acetylsalicylic acid, but it lost its trademark status in the United States, France and the United Kingdom after the confiscation of Bayer's US assets and trademarks during World War I by the United States, and because of the subsequent widespread usage of the word.
The term aspirin continued to be used in the US, UK and France for all brands of the drug, but it is still a registered trademark of Bayer in over 80 countries, including Canada, Mexico, Germany and Switzerland. As of 2011, approximately 40,000 tons of aspirin were produced each year and 10–20 billion tablets consumed in the United States alone for prevention of cardiovascular events. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.
There is an unresolved controversy over the roles played by Bayer scientists in the development of aspirin. Arthur Eichengrün, a Bayer chemist, said he was the first to discover an aspirin formulation that did not have the unpleasant side effects of nausea and gastric pain. He also said he had invented the name aspirin and was the first person to use the new formulation to test its safety and efficacy. Bayer contends that aspirin was discovered by Felix Hoffmann to help his father, who had arthritis. Various sources support the conflicting claims. Most mainstream historians attribute the invention of aspirin to Hoffmann and/or Eichengrün.

Heroin

, now illegal as an addictive drug, was introduced as a non-addictive substitute for morphine, and trademarked and marketed by Bayer from 1898 to 1910 as a cough suppressant and over-the-counter treatment for other common ailments, including pneumonia and tuberculosis. While Bayer scientists were not the first to make heroin, the company did lead the way in commercializing it. Heroin was a Bayer trademark until after World War I. Bayer's director of pharmacology did not want the drug to have "too complicated a name" so Bayer settled on heroisch, the German word for heroic.

Phenobarbital

In 1903, Bayer licensed the patent for the hypnotic drug diethylbarbituric acid from its inventors Emil Fischer and Joseph von Mering. It was marketed under the trade name Veronal as a sleep aid beginning in 1904. Systematic investigations of the effect of structural changes on potency and duration of action at Bayer led to the discovery of phenobarbital in 1911 and the discovery of its potent anti-epileptic activity in 1912. Phenobarbital was among the most widely used drugs for the treatment of epilepsy through the 1970s, and as of 2014 it remains on the World Health Organization's list of essential medications.

World War I

During World War I, Bayer's assets, including the rights to its name and trademarks, were confiscated in the United States, Canada and several other countries. In the United States and Canada, Bayer's assets and trademarks, including the well-known Bayer cross, were acquired by Sterling Drug, a predecessor of Sterling Winthrop and were not reclaimed until 1994.
Throughout the war, Bayer was involved in production and development of various chemical weapons. In 1914, Bayer manufactured dianisidine chlorosulfate for use in 105 mm artillery shell, intended as a lung irritant against British forces.
In 1916, Bayer scientists discovered suramin, an anti-parasite drug that is still sold by Bayer under the brand name Germanin. The formula of suramin was kept secret by Bayer for commercial reasons, but it was elucidated and published in 1924 by Ernest Fourneau and his team at the Pasteur Institute. It is on the World Health Organization's List of Essential Medicines.

IG Farben

In 1925, Bayer became part of IG Farben, a German conglomerate formed from the merger of six chemical companies: BASF, Bayer, Hoechst, Agfa, Chemische Fabrik Griesheim-Elektron, and Chemische Fabrik vorm. Weiler Ter Meer. In the 1930s, Gerhard Domagk, director of Bayer's Institute of Pathology and Bacteriology, working with chemists Fritz Mietzsch and Joseph Klarer, discovered prontosil, the first commercially available antibacterial drug. The discovery and development of this first sulfonamide drug opened a new era in medicine. Domagk won the Nobel Prize in Physiology or Medicine in 1939 "for the discovery of the antibacterial effects of prontosil". He was forced by the Nazi Party to relinquish the reward; German citizens had been forbidden from accepting Nobel prizes since the Nobel committee had awarded the 1935 Nobel Peace Prize to a German pacifist, Carl von Ossietzky.

World War II and the Holocaust

, Bayer's parent company, used slave labour in factories it built in Nazi concentration camps, most notably in the Monowitz concentration camp, part of the Auschwitz camp complex in German-occupied Poland. By 1943, almost half of IG Farben's 330,000-strong workforce consisted of slave labour or conscripts, including 30,000 Auschwitz prisoners.
Helmuth Vetter, an Auschwitz camp physician, SS captain and employee of the Bayer group within IG Farben conducted medical experiments on inmates at Auschwitz and at the Mauthausen concentration camp. In one study of an anaesthetic, the company paid RM 170 per person for the use of 150 female inmates of Auschwitz. A Bayer employee wrote to Rudolf Höss, the Auschwitz commandant: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price."
After the war, the Allied Control Council seized IG Farben for "knowingly and prominently ... building up and maintaining German war potential". It was split into its six constituent companies in 1951, then split again into three: BASF, Bayer and Hoechst. Bayer was at that point known as Farbenfabriken Bayer AG; it changed its name to Bayer AG in 1972. After the war, some employees of Bayer appeared in the IG Farben Trial, one of the Nuremberg Subsequent Tribunals under US jurisdiction. Among them was Fritz ter Meer, who helped to plan the Monowitz camp and IG Farben's Buna Werke factory at Auschwitz, where medical experimentation had been conducted and where 25,000 forced laborers were deployed. Ter Meer was sentenced to seven years, but was released in 1950. Despite being a convicted Nazi war criminal, Ter Meer was elected as chairman of Bayer AG's supervisory board in 1956, a position he retained until 1964.
Helge Wehmeier, then CEO of Bayer, offered a public apology in 1995 to Elie Wiesel for the company's actions during World War II and the Holocaust.
