Question

Who is usually credited with the discovery of penicillin?
A)Fleming
B)Florey and Chain
C)Duchesne
D)Ehrlich

Accepted Answer

Sir Alexander Fleming is typically credited with the discovery of penicillin in 1928. Although others, such as French microbiologist Ernest Duchesne, had observed the antibiotic properties of mold before Fleming, he is widely recognized as the person who first recognized and exploited the therapeutic potential of penicillin. Howard Florey and Ernst Chain, both of whom were part of the team that developed penicillin for clinical use, were later awarded the Nobel Prize in Medicine, along with Fleming. Paul Ehrlich was a German physician and immunologist who made important contributions to the development of antibiotics, but he did not discover penicillin.
