In addition, they received a standing ovation from Oklahoma City University students representing the 130 attending the university under a scholarship bearing Luper's name.
"Fifty years ago, you would think that moment would have stopped right there. But then you walk in here and see all these people,” said Richard Brown, one of the original segregation protesters. "I just couldn't believe it.”
One member of the packed audience said she was there to show support for Luper and the protesters. And she brought her 10-year-old daughter along to give her another perspective on history.
Linda Mitchell is a 42-year-old white homemaker who lives in Crown Heights. She is too young to remember segregation in Oklahoma.
"I think it's important for her to see this, to understand that real people make history. And that history was made in Oklahoma,” Mitchell said, speaking of her daughter who was busy taking pictures of the people sitting on stage. "I never did at her age.”
