This guy was responsible for quite a few interesting discoveries and concepts. It's hard to dodge his influence.
With regards to the last installment they were
Neal Burnette and Harry Towbin who were responsible for developing today's Western blot technique. This site has a good discussion of who deserves most credit - it's a tricky one as it isn't so much a case of "who came up with it first" but rather who came up with the technique that is most often used (and is therefor the most useful). There's no doubt that Burnette coined the name "western blot" in honour of Southern's "southern blot".
