Wynton Marsalis - "Steve Jobs was a man of absolute integrity. He pursued the deepest truths in his imagination with unabashed passion, uncompromising singularity of purpose, and unyielding urgency. Apple's tenacious actualization of his transformative and lofty vision of integration brings us closer together. He was a force of nature, a volcano, and a man who loves and misses his family. The world is much poorer today. And always,” Marsalis said.(Photo: Michael Loccisano/Getty Images)

Rep. John Lewis - A civil rights legend in his own right, Rep. Lewis memorialized the late Rev. Shuttlesworth in a statement. "The Rev. Fred  Shuttlesworth is the last of a kind.  He was a fearless, determined, courageous leader for civil rights and social justice.  When others did not have the courage to stand up, speak up and speak out, Fred Shuttlesworth put all he had on the line to end segregation in Birmingham and the state of Alabama.  He was beaten with chains, his church was bombed, and he lived under constant threat of physical violence and murder,” Lewis said.

Rev. Jesse Jackson - "… His raw courage was that he would not retreat. He never lost his faith in the courts and the law. He always implored the federal government to bring the Constitution to the South for people to whom it had been denied.

U.S. Attorney General Eric Holder - "I was involved in the NAACP in New Jersey during the 1950s and '60s before coming to Cincinnati, and I'd see this man Shuttlesworth on TV, and I'd see him fearlessly confronting racist individuals and a racist system. I said, `I don't think I could do that.' My life was not threatened. My family was not threatened. I always admired him from a distance. When I came to Cincinnati, one of the first things my wife and I did was go to his church, just to see him in person and listen to him. We will not just miss the man, we will miss his spirit of total and unrelenting commitment to obtaining the rights of others that is sometimes missing in the African-American community today,” Holder said.
