. 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.

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

 re-examined the matter and concluded that Eichengrün's account is convincing and correct and that Eichengrün deserves credit for the invention of Aspirin. Bayer promptly denied this theory in a press release, claiming that the invention of Aspirin was due to Hoffmann.

, the controversy is still open: while Sneader's version has been widely reported, there are no independent second sources supporting either version.
