Scholar Manning Marable (pictured, via) has passed away. He was 60-years-old.

Marable served as professor of history and political science at Columbia University. According to The Root, he had been working on the biography Malcolm X: A Life of Reinvention for a decade. Penguin Group (USA) released it today and currently holds the #4 spot on Amazon’s biography & memoirs’ bestsellers list.

His widow, Leith Mullings Marable, shared these thoughts: “I think he would want to be remembered for having contributed to the black freedom struggle. He would want to be remembered for being both a scholar and an activist and as someone who saw the two as not being separated. He believed that both [callings] went together and enhanced each other.”
