Name That Sklar

In a baldfaced exercise in name-dropping, John Judis plugs Martin J. Sklar's magisterial "Corporate Reconstruction of American Capitalism, 1890-1916" in TNR... (and buries the lede: mentioning "that Sklar book" in the first graf but not identifying it until four grafs later.)

Why would this be confusing? Other good Sklar authors on the American beat: Kathryn Kish Sklar and Robert Sklar come to mind... and surely there are others.
