----------------- HES POSTING ----------------- I can't be of much help but can tell you that it's Charles W. Cobb. Cobb was a math professor at Amherst where Douglas encountered him during a sabbatical from Chicago. I recall that Thomas Humphrey wrote a paper on precursors to the C-D function a few years back. I think that's where I acquired this factoid. I don't recall if there's more on Cobb therein. The paper was probably the FRB-RICHMOND Quarterly Review.
