Mad Men is back with us, and the Tribune has alertly linked its home page to a story that ran in Chicago magazine a year ago. “Meet the real Don Draper,” suggests the Tribune, and when we take the suggestion we discover a nostalgic yarn about Draper Daniels, an important Chicago ad man of the 1950s at legendary Leo Burnett who later ran his own agency. “I Married a Mad Man” was written by Daniels’s widow, Myra Janco Daniels, who says Daniels was not only a lot like Don Draper — he helped inspire the TV character.
