Actresses' Franchise League. The Pioneer Players engaged heavily with socio-political issues of the era. The society "acknowledged an interest in women's suffrage and in any other current movement of interest". In 1916, the company produced the play Ellen Young, written by Enthoven and Edmund Goulding. It was performed at the Savoy Theatre on 2 April 1916. In 1921, Enthoven and Cecile Sartoris's translation of Gabriele D'Annunzio's The Honeysuckle played at the Lyceum Theatre (Broadway) in New York, as well as at "Playroom 6" in Soho, London on 9 May 1927. In 1930, The Confederates, a play written by Enthoven in collaboration with H. M. Harwood was produced at the Ambassadors Theatre. Enthoven was an enthusiastic amateur actress and appeared with the "Windsor Strollers", the "Old Stagers" and other prominent amateur companies.

She recalled: "It started when, in 1900, I noticed an inaccuracy in some book of stage history. Being passionately interested in the theatre, I wrote to the author who admitted a mistake. There the matter might have stopped; but soon afterwards I happened to find some old playbills that proved my point. That was when the 'collecting' flea bit me." A chance purchase of two-hundred playbills became the foundation of Enthoven's vast collection, and, after her husband's death in 1910, Enthoven's collecting increased. In 1911, Enthoven mounted a national campaign to establish a permanent theatre collection in a British institution. Writing to The Observer she advocated for: National theatre collections had been established in America at the Harvard Library, in Rome, Milan, Stockholm and Paris, but not
