Richard P. Feynman (1918-1988), scientist, teacher, raconteur, and musician.  Sadly,  a brilliant mind, he assisted in the development of the atomic bomb. He also expanded the understanding of quantum electrodynamics, translated Mayan hieroglyphics, and cut to the heart of the Challenger disaster. And always wanted to visit Tuva,  a small country in the Russian Federation which is famous for its throat singing.
