One of the things that I've found distinctly interesting about the Golden Age of SF is how the authors shape the field that they're in, but also how much one can extrapolate a larger picture out of an author's life. An excellent example of this is Judith Merril, through whom one can find an excellent viewpoint of the shifts in publishing, as well as a number of similarly-high-profiled authors writing at the same time.
Go read The Connections of Judith Merril over on the Kirkus Reviews Blog.
