The late Manning Marable won the [Pulitzer Prize for history Monday](http://www.pulitzer.org/citation/2012-History), honored for a Malcolm X book he worked on for decades but did not live to see published. Marable, a longtime professor at Columbia University, died last year at age 60 just as "Malcolm X: A Life of Reinvention" was being released. The Pulitzer Prize committee called Marables’s book "an exploration of the legendary life and provocative views of one of the most significant African-Americans in U.S. history, a work that separates fact from fiction and blends the heroic and tragic." (The board moved the book from the Biography category to the history category.)
