Bill Moyers talks with Dr. Charles Houston

The life of Charles Houston has been packed with adventure and achievement. Houston has scaled some of the world's towering mountains. His studies of the altitude tolerance of bomber pilots during World War II were crucial in helping the Allies design strategies to defeat Japanese and German flyers. Later, Houston led the first Peace Corps project in India. As a physician, he helped invent a forerunner of the Jarvik artificial heart and is one of the world's foremost authorities on high altitude medicine. And Charles Houston is also an author, having written a number of books documenting his mountaineering adventures and mountaineering science.
