One of my personal heroes is E.O. Wilson, for a variety of reasons. He has done some amazing work for concepts of biodiversity, and entomologists revere him for both his research about ants and his ability to communicate with the general public. In fact, he has won two Pulitzer prizes for his books (among many other awards), so he's kind of a big deal.
Charlie Rose recently did an interview with him on April 3rd about his book The Social Conquest of Earth, and it's fascinating. To watch the video, just follow this link.
