- D’Herelle and Twort: Independently discovered bacteriophages, viruses that infect bacteria, which are now used in phage therapy.
- Beadle and Tatum: Introduced the one-gene-one-enzyme hypothesis, demonstrating that genes dictate enzyme production, foundational to molecular biology.
- Fleming: Discovered penicillin, the first antibiotic, revolutionizing the treatment of bacterial infections.
- Griffith: Conducted experiments showing bacterial transformation, where genetic material from one bacterium can alter another.
