Edward Jenner

The investigation of truth is the noblest employment of the human mind.

My labours have been amply rewarded by the consciousness of having rendered a service to humanity.

The success of vaccination has exceeded my most sanguine expectations.

I have no other object in view than the good of my fellow creatures.

The history of medicine affords no instance of a discovery so important, so universally beneficial, and so rapidly diffused.

It is a source of infinite satisfaction to me to reflect that I have been the humble instrument of so much good.

The greatest reward for a man's toil is not what he gets for it, but what he becomes by it.

I have been so much engaged in the pursuit of this great object, that I have almost forgotten myself.

The path of discovery is not always smooth, but perseverance will overcome all obstacles.

To prevent is better than to cure.

The blessings of vaccination will extend to the remotest corners of the earth.

My heart is full of gratitude for the support I have received.

I consider myself as a citizen of the world, and my labours as devoted to the benefit of mankind.

The more I contemplate the subject, the more I am convinced of its importance.

I have never sought for fame or fortune, but only to be useful to my fellow creatures.

The smallpox, that most dreadful scourge of the human race, is now disarmed of its terrors.

It is a glorious thought that I have been permitted to contribute to the alleviation of human suffering.

The progress of science is slow, but sure.

I have lived to see the day when the practice of vaccination is universally adopted.

My only regret is that I have not been able to do more.
