Pioneering Scientist Erwin Chargaff on the Power of Being an Outsider and What Makes a Great Teacher

In a passage that applies to nearly every field of human achievement, far beyond science, Chargaff revisits the subject of the great teacher’s gift to the student:
If there is such a thing as a great scientist … that greatness can certainly not be transferred by what is commonly called teaching. What the disciples learn are the mannerisms, tricks of the trade, ways to make a career, or perhaps, in the rarest cases, a critical view of the meaning of scientific evidence and its interpretation. A real teacher can teach through his example — this is what the ducklings get from their mothers — or, most infrequently, through the intensity and the originality of his view or vision of nature.
