Fascinating facts about Felix Hoffmann
inventor of Aspirin in 1897.

Felix Hoffmann
Felix Hoffmann, a German chemist, produced a stable form of acetylsalicylic acid, more commonly known as aspirin, in 1897. Hoffmann, was searching for something to relieve his father's arthritis. He studied French chemist named Charles Gergardt's experiments and "rediscovered" acetylsalicylic acid--or aspirin, as we now know it.

The Story:
Felix Hoffmann was born in Ludwigsburg, Germany, in 1868, the son of an industrialist. After finishing school, he initially aimed for a career as a pharmacist. His work in the field of pharmacy fascinated him so much that he decided to broaden his knowledge in this field by studying chemistry. In 1891 he graduated magna cum laude from the University of Munich. Two years later he earned his doctorate, also magna cum laude, after completing his theses entitled "On certain derivatives of dihydroanthracene."

On the recommendation of eventual Nobel Prize laureate Professor Adolf von Baeyer, under whom Hoffmannn had studied, he joined "Farbenfabriken vorm. Friedr. Bayer & Co." in 1894 to work as a chemist in the chemical laboratory.

It was mostly by chance that he made a discovery of historic significance on August 10, 1897. By acetylating salicylic acid with acetic acid, he succeeded in creating acetylsalicylic acid (ASA) in a chemically pure and stable form. The pharmacologist responsible for verifying these results was skeptical at first, yet the extent of this pharmaceutical wonder became clear once several large-scale studies to investigate the substance's efficacy and tolerability had been completed: Hoffmann had discovered a pain-relieving, fever-lowering and anti-inflammatory substance. The company then worked flat out to develop a cost-effective production process that would allow the promising active ingredient to be supplied as a pharmaceutical product. In 1899 it was launched for the first time under the trade name Aspirin, initially as a powder supplied in glass bottles. Aspirin has made the Bayer name world-famous like no other drug product. Shortly after the synthesis of acetylsalicylic acid, Hoffmann was made head of the pharmaceutical marketing department. Two years later he was granted full power of attorney.

In the United States, Bayer was able to obtain a patent, giving the company the monopoly on manufacturing the drug from 1900 to 1917. When Bayer's American plants were sold in 1919 as part of the reparations exacted from Germany after World War I, Sterling Products of Wheeling, West Virginia, was willing to invest the unheard of sum of $3 million for Bayer's drug properties in the United States. But Sterling was unable to protect the trademark status of "aspirin." Aspirin became a staple of the over-the-counter market in the United States and elsewhere.

By the time he retired in 1928, his discovery was already a worldwide success. Yet the "inventor" of Aspirin remained unknown to the international public. He lived in Switzerland out of the public eye until his death in 1946. Felix Hoffmann was never married and had no children.

  • Twice as many people choose aspirin over the personal computer as an invention they couldn't live without in a national survey on inventions conducted by MIT in 1896
  • Americans consume over 50 million aspirin tablets every day, that's over 15 billion tablets a year.
  • The bayer aspirin was originally marketed in loose powder form. In 1900, the company introduced aspirin in tablet form.
  • In 1900, Felix Hoffman was issued a U.S. patent for Aspirin (No. 644,077)
  • The name "aspirin" is composed of a- (from the acetyl group) -spir- (from the spiraea flower) and -in (a common ending for drugs at the time).
