who discovered aspirin

Aspirin in its modern form was first synthesized in 1897 by Felix Hoffmann , a chemist working for the German company Bayer, but its “discovery” is shared across several people and centuries of work on related compounds.

Quick Scoop

• Ancient civilizations used willow bark (which contains salicylates, aspirin’s chemical ancestors) as a pain and fever remedy thousands of years ago.

• In 1763, Reverend Edward Stone formally reported willow bark’s fever‑reducing effects to the Royal Society in London, bringing this folk remedy into scientific discussion.

• In the 1800s, chemists such as Johann Andreas Buchner, Pierre-Joseph Leroux, and Raffaele Piria isolated and refined salicin and salicylic acid, the key precursors to aspirin.

So who “discovered” aspirin?

From a modern perspective, most history and medical texts credit Felix Hoffmann at Bayer with creating the first stable, pharmaceutically useful form of acetylsalicylic acid (ASA) — the drug that would be branded as “Aspirin.” He prepared a pure sample of ASA on 10 August 1897, motivated (according to the classic Bayer story) by a desire to help his father, who could not tolerate the stomach irritation caused by sodium salicylate.

However, the story is more tangled:

• The French chemist Charles Frédéric Gerhardt had already synthesized an impure form of acetylsalicylic acid in 1853, but he did not develop it as a medicine and his method was not exploited commercially.

• Later, chemists like Hugo von Gilm and Karl Kraut improved understanding and methods around related acetylated salicylic compounds, setting the stage for a more practical synthesis.

• Decades after Hoffmann’s work, Arthur Eichengrün , another Bayer chemist, claimed he had actually directed the development of ASA and that Hoffmann merely followed his instructions, sparking a long‑running debate about who deserves primary credit.

Because of these overlapping contributions, many historians say aspirin “has many fathers”: folk healers who used willow, early chemists who isolated salicin and salicylic acid, Gerhardt who first made acetylsalicylic acid, and Hoffmann (and possibly Eichengrün) who turned it into the stable, widely usable drug that became a global staple.

Mini timeline of the aspirin story

1. Ancient times – Sumerians, Egyptians, Greeks and others use willow and related plants to relieve pain and fever, without knowing the exact active compound.

2. 1763 – Reverend Edward Stone documents that powdered willow bark reduces fevers, giving an early scientific report of salicylate effects.

3. 1828–1838 – Buchner, Leroux, and Piria isolate salicin and convert it to salicylic acid, which becomes a powerful but stomach‑irritating drug.

4. 1853 – Charles Frédéric Gerhardt produces acetylsalicylic acid, but the product is impure and not marketed as a medicine.

5. 1897–1899 – Felix Hoffmann (under Bayer) synthesizes a pure, stable form of acetylsalicylic acid and Bayer introduces it as “Aspirin,” which rapidly spreads worldwide.

So, if the question is “who discovered aspirin?” in the everyday sense, the usual answer is Felix Hoffmann at Bayer in 1897, with an important historical footnote that many other scientists and earlier remedies paved the way to that moment.
