J.D. Salinger, the legendary author, youth hero and fugitive from fame whose 'The Catcher in the Rye' shocked and inspired a world he increasingly shunned, has died. He was 91. Salinger died of natural causes at his home on Wednesday, the author's son said in a statement from Salinger's literary representative. He had lived for decades in self-imposed isolation in the small, remote house in Cornish, N.H.
