American journalism has lost one of its elder statesmen. Walter Cronkite was one of the founding fathers of broadcast journalism, pioneering a warm, conversational style for delivering facts with detachment and gravitas. The old-style newsman delivered news to the American viewing public about John F. Kennedy’s assassination, the civil rights movement, the Vietnam war, the protests of the 1960s, the Moon landing (40 years ago Monday), Watergate and other major moments of crisis and achievement.
