An alternative credit for developing aspirin has also been offered. In 1949, ex-Bayer employee Arthur Eichengrün published a paper in Pharmazie, in which he claimed to have planned and directed Hoffman's 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.Eichengrün A. 50 Jahre Aspirin. Pharmazie 1949;4:582-4. (in German) Eichengrün died the same month he published in Pharmazie.
