In her book "Sexualizing Power in Naturalism: Theodore Dreiser and Frederick Philip Grove", Irene Gammel examined the gender relationships of Grove's fiction, focussing in particular on his sexualized (and modern) female figures and the overexposed relationships of power. Gammel also traced Grove's relationship with Elsa Plötz (Baroness Elsa) in her biography "Baroness Elsa: Gender, Dada, and Everyday Modernity", documenting that the couple had been legally married and that Grove's reasons for hiding his identity had much to do with his fear of being discovered by his former wife, the dada artist Baroness Elsa. It has also been argued, by Martens in "Over Canadian Trails", perhaps more persuasively, that Greve understandably changed his identity in order to escape internment as a German national at the outbreak of the Great War.
