As a Cinema Studies grad student at NYU in the 1970s, I had to submit a final paper that was the equivalent of a master's thesis—although the department didn't call it a thesis. Anyway, Jules Furthman was the subject of my "thesis." A few years later, an abridged version appeared (under Renée D. Pennington, my maiden name) in the Dictionary of Literary Biography, Vol. 26: American Screenwriters (1984), pp. 119–128. If you're curious, some libraries in the U.S. may still have a set of this series.
