Felix Hoffmann (21 January 1868 – 8 February 1946) was a German chemist notable for re-synthesizing diamorphine (independently from C.R. Alder Wright who synthesized it 23 years earlier), which was popularized under the Bayer trade name of “heroin”. He is also credited with synthesizing aspirin, though whether he did this under his own initiative or under the instruction of Arthur Eichengrun is contested.
