Penicillin cures, but wine makes people happy.

Penicillin sat on a shelf for ten years while I was called a quack.

Nature makes penicillin I just found it.

It was astonishing that for some considerable distance around the mould growth the staphococcal colonies were undergoing lysis. What had formerly been a well-grown colony was now a faint shadow of its former self...I was sufficiently interested to pursue the subject.

For the birth of something new, there has to be a happening. Newton saw an apple fall James Watt watched a kettle boil Roentgen fogged some photographic plates. And these people knew enough to translate ordinary happenings into something new.

The unprepared mind cannot see the outstretched hand of opportunity.

(The discovery of penicillin) was a triumph of accident, a fortunate occurrence which happened while I was working on a purely academic bacteriological problem.

One sometimes finds what one is not looking for.

Suggested remedy for the common cold: A good gulp of whiskey at bedtime-it's not very scientific, but it helps.

One sometimes finds what one is not looking for. When I woke up just after dawn on Sept. 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did.

If penicillin can cure those that are ill, Spanish sherry can bring the dead back to life.
