Recently I read Norman Cantor's "Inventing the Middle Ages". It's a history of Medieval Studies in the 20th century as seen from the lenses of the biographies of a dozen or so individuals, focusing on their development, the historical trends, their relation with the culture and events of the past century etc. I had know Pfeiffer's two volumes on "The History of Classical Scholarship", but that goes up until the 1850s. I was wondering if there is anything like that for the 20th century, or at least if anything comes close.
