I've finished bios of Clarence Darrow and Clara Foltz (who, as you may know, was the first woman lawyer in California, successfully argued her own case to open up Hastings law school to women, and proposed the creation of what we'd now call the public defender's office). If you like reading about lawyering, you will enjoy both. (At Legal History Blog, there is a post about a different Darrow bio. There are quite a few to choose from, including Darrow's auto-biography.)
A while back, I floated the idea of teaching a PR course through bios and historical books. As I've mentioned before, the Dircks and Steiner books on Lincoln's legal career are great from a law of lawyering prespective.
