Felix Hoffmann (January 21, 1868 – February 8, 1946) was a German chemist, credited for the first synthesized medically useful forms of heroin and aspirin, though some sources maintain that Arthur Eichengrün was the real creator of the latter. Hoffmann was born in Ludwigsburg and studied Chemistry in Munich. In 1894, he joined the Bayer pharmaceutical research facility in Elberfeld.
He is best known for having synthesized acetylsalicylic acid (ASA) on August 10, 1897, for the first time in a stable form usable for medical applications. Bayer marketed this substance as Aspirin. However, this has been disputed. In 1949, Arthur Eichengrün published a paper in which he claimed to have planned and directed the synthesis of Aspirin along with the synthesis of several related compounds. He also claimed to be responsible for Aspirin's initial surreptitious clinical testing. Finally, he claimed that Hoffmann's role was restricted to the initial lab synthesis using his (Eichengrün's) process and nothing more.[1]
The Eichengrün version was ignored by historians and chemists until 1999, when Walter Sneader of the Department of Pharmaceutical Sciences at the University of Strathclyde in Glasgow re-examined the matter and concluded that Eichengrün's account is convincing and correct and that Eichengrün deserves credit for the invention of Aspirin.[2] Bayer promptly denied this theory in a press release, claiming that the invention of Aspirin was due to Hoffmann.
As of 2004[update], the controversy is still open: while Sneader's version has been widely reported, there are no independent second sources supporting either version.
Both substances had been synthesized earlier, but not in forms that could be used for medication. ASA had first been synthesized by Frenchman Charles Frédéric Gerhardt in 1853, and diacetylmorphine (that is, heroin) by C.R. Alder Wright, a British chemist in 1873.
Following the synthesis of aspirin, Hoffmann changed to the pharmaceutical marketing department, where he stayed until his retirement in 1928. In 2002, he was inducted into the US National Inventors Hall of Fame.
