Dan Rather was the first to report John F. Kennedy's death in Dallas. He sparred with Richard Nixon during the Watergate era. And from 1981 to 2004, he was the anchorman and managing editor for the CBS Evening News -- a job that took him from Soviet-occupied Afghanistan to war-torn Bosnia, from 9.11 to the war in Iraq. Now, in this first-ever full-scale biography, a long-time writer and producer at CBS News delivers the inside story on Rather and his times.
