Ernst Mayr - The Double Helix
He, more than anybody else except maybe Linus Pauling, [felt that]…the structure of the DNA at that moment of history was the most important thing in biology. When he worked with Francis Crick-very often one factors Ph.D. thesis or all sorts of some other things- and Watson was always the one who always said, "By god, we got to work on this DNA that's the important thing!" So he deserves credit for that one! As far as knowledge of the subject matter is concerned, Watson had none (laughter). But he knew the one important thing-what's that famous Isaiah Berlin statement? [What's] the difference between the fox and the hedgehog, you know. If you know the one important thing, that's really what counts-and that was Watson's greatness!
