It is difficult to find a historian who questions the orthodoxy. Gene Smiley’s book The American Economy in the Twentieth Century challenges it, but he is very much in the minority. You might look at Robert Higgs’s book Depression, War, and Cold War, and follow the footnotes to uncover the specific people he identifies (though he may be sparring more with economists than with historians). But seriously, the only problem you will have will be in finding historians who question the war prosperity.
