A&E’s Biography series will profile “Civil Rights Heroes” — specifically some of those who have worked to keep Martin Luther King’s dream alive — as Black History Month draws to a close. It’s a diverse group. Ruby Dee and Ossie Davis, married for 50 years now, will talk about their belief that the trip to the promised land is far from over. The program will also focus on Irene Morgan Kirkaldy, who refused to give up her seat to a white passenger on a Greyhound bus in 1944. It was the Supreme Court’s ruling in her case that overturned Jim Crow laws in interstate busing. Former Boston Celtics basketball star Bill Russell will be profiled. He became the first black head coach in the NBA. The program will also take a look at Mae Bertha Carter’s eight children, who were the only black students in their county’s formerly all-white schools in 1965, the year school segregation ended in Mississippi. All eight went on to graduate from college. Also on A&E’s list is John Lewis, one of those who organized the march on Washington in 1963. In 1965, he led 525 marchers across the bridge in Selma, Ala., and into the clutches of waiting police. Now Lewis is a member of the U.S. House. Harry Smith is the host of the broadcast on Wednesday, Feb. 28, at 8 p.m.
