DBusiness is a stylish and well-edited magazine devoted to the Detroit business scene. (Click on the magazine page to the left to link to the DBusiness website.) The story you see here is based on archival research I’ve pursued in the National Automotive History Collection, which is one of the special collections at the Detroit Public Library. I’ve read the papers of the Knudsen Family Archive. It comprises the personal collections of Big Bill Knudsen, who ran the Chevy Division throughout the 1920s and became GM’s president in 1937, and his son, Bunkie, who ran Pontiac in the late 1950s and then Chevy for a few years in the 1960s. Bunkie kept a diary, which proves most illuminating. “The Last Golden Age” is a précis of the whole, sprawling tale of Bunkie’s Shakespearean rivalry with the great Ed Cole. Both men wanted to be GM president. After Cole prevailed in this rivalry in 1967, Bunkie checked out and went to Ford as president for nineteen months, until his undoing at the hands of Lee Iacocca.
