Paul Ehrlich

We must not be afraid to experiment.

The greatest discoveries are often made by accident, but only to those who are prepared.

The more we know, the more we realize how much we don't know.

The fight against disease is a continuous one.

The human body is a marvel of chemical engineering.

We must always strive for perfection, even if it is unattainable.

The true scientist is driven by curiosity, not by fame or fortune.

The laboratory is my sanctuary.

The greatest reward is to see your work benefit humanity.

We are only scratching the surface of what is possible in medicine.

The more complex the problem, the more elegant the solution must be.

The history of medicine is a history of progress, often slow, but always forward.

To conquer disease, we must understand its essence.

The future belongs to those who dare to dream.

My life has been dedicated to the service of science and humanity.

The path to discovery is paved with failures.

Let us not be content with what we know, but always strive for more.

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

We must shoot with 'magic bullets' at the enemy, not at the patient.

If a man has a hundred ideas and one of them is good, he is a genius.
