Defense Attorney: So while no cures can be attributed to '606,' 38 deaths resulted from it's use?
Dr. Emil Von Behring: 39.
Defense Attorney: 39? You know of another death?
Dr. Emil Von Behring: Yes, syphilis. The death of syphilis itself.
Dr. Hans Wolfert: Dr. von Behring you have written and lectured against the Ehrlich theory.
Dr. Emil Von Behring: Yes, I did, Dr. Wolfert, but you must understand it is the task of science to discover the truth. There is no shame attached to the recognition of error.

Dr. Paul Ehrlich: [His final message, on his deathbed, to his research team] There will be epidemics of greed, hate and ignorance. We must fight them in life as we fought syphilis in the laboratory. We must fight, fight. We must never, never stop fighting.

Dr. Paul Ehrlich: I want no legal advice. This is a question of truth. I'm only trying to help the court understand the real nature of these deaths.
Judge: Dr. Ehrlich, I'm afraid your observations are irrelevant to this issue.
Dr. Paul Ehrlich: [In perplexed astonishment] Irrelevant?... Irrelevant?
