'Humankind' documentary creator David Freudberg celebrates 50 years on air

Fifty years ago this month, journalist David Freudberg filed his first story for National Public Radio. He was 16 years old.

Later, he became the founder and executive producer of Human Media. He has scored interviews with everyone from the Dalai Lama to Muhammad Ali to a 29-year-old Joe Biden right after Biden was elected to the Senate.

About 25 years ago, Freudberg created "Humankind," a program that blossomed from his interest in the human spirit. He talks with host Lisa Mullins about his career and the high moments.
