We shall not see his like again.
UPDATE: Here's what the New York Times said:
How very, very true.
Mr. Cronkite anchored the “CBS Evening News” from 1962 to 1981, at a time when television became the dominant medium of the United States. He figuratively held the hand of the American public during the civil rights movement, the space race, the Vietnam war, and the impeachment of Richard Nixon. During his tenure, network newscasts were expanded to 30 minutes from 15.
“It is impossible to imagine CBS News, journalism or indeed America without Walter Cronkite,” Sean McManus, the president of CBS News, said in a statement. “More than just the best and most trusted anchor in history, he guided America through our crises, tragedies and also our victories and greatest moments.”
Mr. McManus added: “No matter what the news event was, Walter was always the consummate professional with an unparalleled sense of compassion, integrity, humanity, warmth, and occasionally even humor. There will never be another figure in American history who will hold the position Walter held in our minds, our hearts and on the television. We were blessed to have this man in our lives and words cannot describe how much he will be missed by those of us at CBS News and by all of America.”
