TERRY GROSS, HOST:
This is FRESH AIR. I'm Terry Gross. Pulitzer Prize-winning journalist and bestselling author Tony Horwitz died Monday unexpectedly at the age of 60. He was in the middle of a book tour promoting his new book, "Spying On The South." He's survived by his wife, the journalist Geraldine Brooks, and their two sons. Before becoming a full-time author, Tony Horwitz covered wars and conflicts in Northern Ireland, Bosnia and Iraq for The Wall Street Journal. He won a Pulitzer Prize in 1995 for his stories about working conditions in low-wage America.
