Alexander Fleming

The discovery of penicillin was a stroke of luck, but it was also the result of many years of hard work.

I hope that my work will inspire others to pursue scientific discovery.

The impact of penicillin on modern medicine is immeasurable.

It is a wonderful thing to be able to save lives with a simple substance.

I never sought fame or fortune, only to contribute to human knowledge.

The power of observation is crucial in scientific research.

I am just a simple bacteriologist who got lucky.

The greatest danger in the world is ignorance, and the greatest weapon is knowledge.
