1. [Aiken, Henry David] Knopf, Alfred A.

Scathing Typed Letter signed from eminent publisher Alfred A. Knopf to Philosopher Henry David Aiken, who promised him to deliver the book “Pragmatism Revisited” two years prior and who he had already reminded twice about deadlines which had been ignored by Aiken. Knopf, famous for his lengthy correspondence, asks for the advance to be returned and expresses his disappointment in no uncertain terms: “….this makes me feel that you have lost all interest in having this book published by Knopf…..you seemed to be so friendly and so interested in our house when I did meet you in Boston that I hesitate to take this action….”. [The letter, from the personal collection of Henry David Aiken, is accompanied by an original typescript of Aiken’s apologetic response to Knopf. Acccording to our sources, this book never saw the light of day].
