PORT-AU-PRINCE, Haiti (AP) -- George Corvington, a prominent Haitian historian best known for his exhaustive study of the Caribbean nation's capital of Port-au-Prince, died Wednesday at age 88, a close friend said. Fellow historian and longtime friend Georges Michel said that Corvington died peacefully in his sleep at his home in the capital he wrote so much about. Michel said Covington had recently spent a few weeks in the hospital and the cause of death was heart failure. "He's a giant that has fallen," said Michel, who is also a physician. "He was the greatest living Haitian historian."
