What was penicillin made from
Beginning in , after news reporters began to cover the early trials of the antibiotic on people, the unprepossessing and gentle Fleming was lionized as the discoverer of penicillin. That problem was partially corrected in , when Fleming, Florey, and Chain — but not Heatley — were awarded the Nobel Prize in Physiology or Medicine.

Penicillin clearly led the way in that development.
