Edwin Moses is recognized as one of the greatest athletes in the world. The Olympic champion used science and math calculations to dominate track and field. He went undefeated in the 400-meter hurdles for 122 consecutive races, for nine years, nine months, and nine days, between 1977 to 1987. But his life’s legacy reaches beyond sports and is now being told in a documentary, “MOSES-13 Steps.”  Moses talks with show host Rose Scott about the film that will debut at the 6th Annual Morehouse College Human Rights Film Festival on Saturday, Sept. 21.
