How many lives did penicillin save?

Penicillin, the world’s first antibiotic, has since saved an estimated 200 million lives.

When did Alexander Fleming publish his discovery of penicillin?

Alexander Fleming’s Discovery of Penicillin. It proved to be very unstable, and they were only able to prepare solutions of crude material to work with.
