David Garnett (1892-1981) is mostly known for his minor role as a member in the Bloomsbury Group, meeting in WWI. The Bloomsbury Group is made up of artists, writers, and even a famous economist during the early twentieth century, i.e. Virginia Woolf, Lytton Strachey, and John Maynard Keynes. Scholars rarely notice or even mention Garnett’s impact in shaping modernism as a writer, critic, and editor, especially in London. In this dissertation, I utilize Garnett’s personal letters housed at the Harry Ransom Center at the University of Texas as well as research surrounding the Bloomsbury Group to reveal Garnett’s significant and often underestimated role. Meaning in the Margin posits as an important and resourceful writer of the time. His letters during WWI show a young man in transition, revealing his struggles as a conscientious objector and his developing relationship with the Bloomsbury Group. The letters after WWI highlight a knowledgeable writer and critic in London, expanding a network of his own. Garnett’s novels, Lady into Fox (1922), A Man in the Zoo (1924), The Sailor’s Return (1925), Go She Must! (1927), Beany-Eye (1935), and Aspects of Love (1955), emphasize a concern for the psychological and man’s relationship to the animal. This work concludes Garnett is worthy of attention for scholars due to his letters and literary contributions.
