Name the Biologist

I only found out about this guy after attending a lecture this week. He's an interesting character in that his political views actually set back a field in Biology by half a century!

And for those who can cast their minds back a few months - here's the answer to the previous installment.

It was Matthew Meselsohn and Werner Arber for their development of restriction enzymes (although they are famous for quite a lot of things) which are an essential tool for any biologist wanting to clone pieces of DNA into various useful vectors. I'd have a lot less GFP tagged proteins if not for them.
