For five decades journalist and storyteller Tom Brokaw served as a pillar of NBC News, reporting from such hotspots as Tiananmen Square and the Berlin Wall. His 1998 book, “The Greatest Generation,” became a bestselling testimonial to the men and women who selflessly fought, and won, World War II. Then, six years ago he was diagnosed with multiple myeloma. Brokaw talks about his fight to overcome bone marrow cancer with “Sunday Morning” host Jane Pauley, his former colleague from the “Today” show. Source
