1. Paulescu’s Pancrein

The discovery of insulin was no doubt a major breakthrough in medicine—prior to its discovery, diabetes sufferers often died at a young age. But while Canadian scientists Sir Frederick G. Banting and Charles H. Best, along with their colleagues, often are credited with the hormone’s discovery and isolation, Romanian physiologist Nicolas C. Paulescu appears to have beaten them to it. Paulescu isolated a substance called “pancrein,” presumably insulin, in 1916, but he was soon after recruited to serve in World War I. He finally published his findings in 1921, though they were overshadowed by the release of the Canadians’ report early the following year.

2. Aspirin

In 1899 Farbenfabriken vormals Friedrich Bayer & Co. (later Bayer AG) introduced aspirin, a pain-reliever that would come to rank high among the world’s most commonly used drugs. The company credits the synthesis of pure acetylsalicylic acid, aspirin’s active ingredient, to Bayer chemist Felix Hoffmann. However, decades after its introduction, former Bayer chemist Arthur Eichengrün cried foul, claiming to have invented the process of the compound’s synthesis himself, with Hoffmann merely carrying out the procedure. Bayer holds by its claim that Hoffmann was the inventor.
