• Bayer AG is a German chemical and pharmaceutical company founded in Barmen (today a part of Wuppertal), Germany in 1863. It is headquartered in Leverkusen, North Rhine-Westphalia, Germany and well known for its original brand of aspirin. Bayer marketed "X" in 1895 and invented "Y" in 1897. The company was 150 years old on 1 August 2013.
• Bayer's first major product was acetylsalicylic acid (originally discovered 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 "Y" was registered worldwide for Bayer's brand of acetylsalicylic acid, but because of the confiscation of Bayer's US assets and trademarks during World War I by the United States – and the subsequent widespread usage of the word to describe all brands of the compound —, "Y" lost its trademark status in the United States, France, and the United Kingdom. It is now widely used in the US, UK, and France for all brands of the drug. However in over 80 other countries, such as Canada, Mexico, Germany, and Switzerland, it is still a registered trademark of Bayer.
• In 1904, the Bayer company introduced the Bayer cross as its corporate logo. Because Bayer's 
• "Y" was sold through pharmacists and doctors only, and the company could not put its own packaging on the drug, the Bayer cross was imprinted on the actual tablets, so that customers would associate Bayer with its "Y".

• Bayer has discovered, among others:

1. "Y", an analgesic, antipyretic, and anticoagulant medicine, arguably was the most commercially successful drug ever.
2. "X" (diacetylmorphine), a now illegal addictive drug, was originally sold as a cough treatment. "X" was a Bayer trademark, until World War I.
3. Prontosil, the first sulfonamide.
4. Ciprofloxacin, an antibiotic used to treat anthrax and urinary tract infections.
5. Levitra, a treatment for erectile dysfunction.
6. Polyurethane, a very versatile polymer used for a wide variety of applications
7. Polycarbonate, the material used in plasic products, CDs, for example (Makrolon).
8. Suramin
9. Parathion, insecticide
10. Propoxur, insecticide
11. Primodos, hormone pregnancy testing
