In this article Helen Grime examines the enduring epithet of ethereality and its persistent connection to the career of the actress Gwen Ffrangcon-Davies (1891–1992). Most closely associated with her portrayal of Etain in the much revived musical drama The Immortal Hour, ethereality is understood as a signifier of 1920s femininity. The offstage presentation of a domesticated femininity further evidences the apparent conventionality of this actress's self-presentation at a time of particular anxiety about the socio-political position of women. These notions of femininity hint at the prevailing social attitudes that confronted an actress whose on- and offstage appearances were subject to public scrutiny while her private lesbian identity remained obscured. It is suggested, however, that Gwen Ffrangcon-Davies's playful negotiation of her demonstrably fragmented identity evidences an agency and self-possession belied by her public conformity. Helen Grime completed her thesis, A Strange Omission: Gwen Ffrangcon-Davies, Twentieth-Century Shakespearean Actress, in 2008 and is currently a Lecturer in Drama at the University of Winchester.
