Which era is the era of 'The Pound Era'?

fragment of a letter written by Hugh Kenner in 1960

Hugh Kenner's huge (and hugely important) book on Pound was published in 1971. A book of its time? Well, considering the social and politcal context of 1971: maybe The Pound Era is a book running counter to the trend of its time. But never mind those assumptions. The book was first planned in....1960. Eleven years earlier. This startling fact I learned a lttle while ago when I read some unpublished Kenner correspondence in Chicago.
