Isaac Asimov thought of himself a "professional explainer;" and, even without Youtube and the Internet, I always thought he undoubtedly must be the world's greatest. Since Asimov's death in 1992, it seems clear that his mantle has fallen on Richard Dawkins.
I can only wish I had that kind of talent, knowledge, and ability to explain science simply and interestingly. And I do wish it. Desperately.
