There are a few but one that really struck me is Dr Barry Marshall.
I would say he is a really brave and a bit of a nutter. Basically, Dr Warren and Dr Marshall had a prediction. They predicted Helicobacter. pylori (a bacterium) is one of the causes for stomach cancers. But it was very hard to grow H. pylori in the lab and people didn’t really believe them.
So one day, Dr Marshall just swallowed a live sample of the bacterium (taken from his patient) and he then developed the same illness too and proved his point.
I don’t know if you get old episodes of his show over here, but my favourite scientist is Bill Nye. He is an engineer by training but gave it up to do science outreach instead. His show Bill Nye – The Science Guy came out while I was at university. It was designed to teach kids about science and it was the first programme that really got me thinking about how to communicate science.
I really like Stephen Hawking (http://www.hawking.org.uk/). He is quite possible the most brilliant mind of our time. Where other people struggle even understanding what the problem is about, he seems to come up with the solution just like that. And I really like what he studies! 🙂
