As part of my research methods course, I teach about cumulativity and collaboration in the achievement of scientific progress.  I recently read James Watson's book "The Double Helix" (published in 1968, but only recently appearing on the discount table at a local bookstore) on the 1953 discovery by him and Crick of the structure of the DNA molecule.  Given my teaching on scientific progress and fascination with social networks, I decided to map out the network of assistance Watson and Crick received while working on the DNA structure.  Other, more extensive work has been done on the network of paper citations leading to the DNA structure discovery and within social psychology, Paul Rozin had a nice discussion of the build-up to Watson and Crick's discovery (which I cite in a write-up accompanying my diagram).  My emphasis was more on the beneficial day-to-day interactions in the lab that Watson wrote about.  Please take a look by clicking on:
