One day at Princeton, I noticed there were dead birds on the pavement between the campus buildings, where very large trees were. It turns out it was DDT. At the time, in the early '50s, no one thought DDT was dangerous to anybody but insects. I went down to the Daily Princetonian, the college paper, and tried to persuade them to do a story. They said, "Naw, there's nothing wrong." But that taught me a very important lesson. One, that newspaper people can get very jaded. Second, that you might know something, like an expert chemistry professor, you are not going to apply what you know.
