Felix Hoffmann patented one of the world’s most common drugs, Aspirin (acetylsalicylic acid).

Known to doctors since the mid-19th century, it was used sparingly due to its unpleasant taste and tendency to damage the stomach. In 1897, Bayer employee Felix Hoffmann found a way to create a stable form of the drug that was easier and more pleasant to take. (Some evidence shows that Hoffmann’s work was really done by a Jewish chemist, Arthur Eichengrun, whose contributions were covered up during the Nazi era.) After obtaining the patent rights, Bayer began distributing aspirin in powder form to physicians to give to their patients one gram at a time. The brand name came from “a” for acetyl, “spir” from the spirea plant (a source of salicin) and the suffix “in,” commonly used for medications. It quickly became the number-one drug worldwide.
