CBS News correspondent Mike Wallace died this weekend in New Canaan, Connecticut. He was 93. Wallace was one of the original co-hosts for CBS' "60 Minutes" when it debuted in 1968. In his nearly four decades with the program, he became one of the country's best-known broadcast journalists. He interviewed everyone from Louis Farrakahn to Roger Clemens and even Iranian President Mahmoud Ahmadinejad. Former CBS Moscow Bureau Chief Beth Knobel  co-authored the book "Heat and Light: Advice for the Next Generation of Journalists" with Wallace. She remembers Wallace not just as pioneering broadcast journalist – but as a warm, inspired colleague.
