If find it hard to recount Dick’s [Richard C. Lewontin] scientific accomplishments—not because I don’t know them, but because they’re already well known and you can read about them in many places. He made fundamental contributions in theoretical population genetics, in experimental population genetics (out of his lab came the first assays of genetic variation at individual loci using both electrophoresis and DNA sequencing), and even in ecology. He never wrote a trivial paper.
