Chapter 4 plays mainly between Washington, DC, and Pacific Palisades, CA. I present the writer Thomas Mann as part of the memorandum culture fighting against Nazi Germany and I demonstrate, what a literary-critical analysis of his work looks like, if one takes his job situation in the early 1940s into account: Consultant to the Library of Congress, appointed by Archibald MacLeish. For this purpose, I highlight the central role of Mann’s various collaborations – on various scales and levels of intensity – with folklorist Gustave O. Arlt and scholar Joseph Campbell, critical theorist Theodor W. Adorno and journalist Agnes E. Meyer in the making of Doctor Faustus. I reflect on the first publication of Mann’s Doctor Faustus as a mimeographed copy, I revisit his choice of the name Leverkühn for the novel’s protagonist, I elucidate his concept of montage, and I underline the social scientific aspects of the novel.
