Does wearing a beret mean you're a crap scientist?

Dr Chris Busby, principal scientific adviser to the Low Level Radiation Campaign, invariably wears a beret. Some people think the paramilitary connotations undermine his credibility. Perhaps it has deceived The Independent's "science" editor, Steve Connor, into thinking of Busby as merely a green activist (see see 8th November article).
Busby's cv is on this site. If Steve Connor would care to supply his own, we'll post it as well.

Another scientist with a mission and a hat.
The late Linus Pauling, the only man in the world to have won two unshared Nobel Prizes. His biographers say Two Nobel Prizes by one man in one lifetime! - 1954, for Chemistry, and 1962, for Peace.
Linus Pauling was globally admired and globally controversial. In 1958, he presented a petition, which was signed by 11,000 scientists, warning the public about the biological danger of radioactive fallout from nuclear weapons testing.
