Mike Wallace, professional.

Mike Wallace, the tough interviewer who formed the backbone of “60 Minutes” in its heighday, and who was one of the last links to the Golden Era of Walter Cronkite and Edward R. Murrow, when broadcast journalism was seen as a public service rather than entertainment and partisan sport, has died. That’s amazing in itself, for I had come to believe that he would live forever. He was only 93.

There will be many tributes to Wallace in the coming days, but for now, you can remind yourself of his remarkable career here. Mike Wallace performed a difficult job well longer than anyone else, and he always strived to meet the highest ethical standards in a profession that once had some.

He will be missed.

Hell, he was already missed.
