Martha Gellhorn and Ernest Hemingway met in Key West in 1937, married in 1941, and divorced in 1945. Gellhorn's work exhibits a strong influence from Hemingway's work, including collaboration on her work during their marriage. I will discuss three of her six novels: WMP (1934), Liana (1944), and Point of No Return (1948). The areas of influence that I will rely on in many ways follow the stages Harold Bloom outlines in Anxiety of Influence. Gellhorn's work exposes a stage of influence that Bloom does not describe-which I term collaborative. By looking at Hemingway's influence in Gellhorn's writing the difference between traditional literary influence and collaborative influence can be compared and analyzed, revealing the footprints left in a work by a collaborating author as opposed to simply an influential one.
