NEW YORK (CBSNewYork/AP) — Chris Wallace turned and blew a kiss to a giant portrait of his father, “60 Minutes” journalist Mike Wallace, after memorializing him Tuesday as “the best journalist I have ever known.”

For nearly two hours, colleagues, friends and family members swapped stories, some flattering, some not so, about one of television news’ best-known journalists.

Wallace, who left an indelible imprint on broadcast journalism during his 68 year-long career, died April 7 at the age of 93.

Despite exasperating moments, he was loved because he was not mean and had a good heart, his son said. As dementia began stripping away his intellect in his final years, “what remained of Mike Wallace was a sweet and gentle man,” he said.

Wallace is best known for his work on “60 Minutes,” but his long career includes stints as a game show host, actor and radio host.

He retired as a regular correspondent in 2006, but appeared occasionally on “60 Minutes” until heart surgery slowed him down in 2008.

Besides Chris Wallace, two of Mike’s grandchildren, former colleagues Steve Kroft and Morley Safer and CBS News Chairman Jeff Fager also spoke.
