"Surely You're Joking Mr. Feynman!"
That's the title of a set of books, written by Richard P. Feynman, one of the greatest physicists of our century. Not only was he brilliant in his profession, theoretical physics (which won him the nobel prize), he was also a remarkable lecturer, story teller and finally also bongo player. He died in 1988.
His lectures where crowded with students, everyone wanted to learn from him. He had the ability to explain the most complex relations in simple words giving even "outsiders" of physics a chance to understand what's going on.
His "Feynman Lectures on Physics" (three volume books on the basics on physics) are still the most popular books for students.
Last year I was happy finding an audio cd collection containing original recordings of his lectures from 1961-63. I was even more happy realizing I was able to follow his explanations 
Beside these books on physics he also wrote books full of hilarious anectodes of his life, his childhood, his time in Los Alamos working in the atomic bomb project during WW2, his time in the commission to figure the reason for the Challenger desaster in 1986, and much more.
If you are looking for a list of Feynman books you can use a list I have colleted years ago:
The "Feynman Lectures on Physics" are missing on this list, but you can get them from Amazon (amazon.de / amazon.co.uk)
If you want to get an idea of his ability to teach there is a very seldom chance to watch him teaching. In 1979 a series of his lectures has been video taped in course of the "The Douglas Robb Memorial Lectures". In more then four hours you can follow Feynman into photons, electrons and quatums.
All of it is highly recommended !
