Scientific Context ▼
Before the 20th century, bacterial infections were highly lethal due to a lack of targeted medications.

Medical Revolution ▼
Fleming isolated the mold's active bacteria-killing substance, creating what became recognized as the world's first widely effective antibiotic medicine.
Conclusion ▼
Penicillin is universally celebrated as Fleming's monumental 1928 discovery.
