Alexander Fleming

I was not looking for penicillin, but I found it.

The greatest discovery of all time is that a man can change his future by merely changing his attitude.

The first thing I did was to make sure that it wasn't just a fluke.

It has been said that I was lucky. Perhaps I was. But I think it is more than luck.

The bacteriologist must be a man of infinite patience.

I have no doubt that penicillin has saved more lives than any other drug.

The development of penicillin was a team effort.

It is the duty of the scientist to make his discoveries available to all.

The greatest reward for a scientist is the knowledge that his work has benefited mankind.

I am a simple bacteriologist, and I have done my best.

The mold was a contaminant, but it turned out to be a blessing in disguise.

The discovery of penicillin was a happy accident.

We must be careful not to abuse the power of antibiotics.

Science is a continuous process of discovery.

I have always been interested in the unseen world of microbes.

The power of observation is essential for any scientist.

The world is full of wonders, if only we take the time to look.

My work has been a labor of love.

The greatest satisfaction comes from knowing that one's work has made a difference.

We must never take our health for granted.
