Treadwell was only peripherally involved in the movement through her work at the Provincetown Players during their early existence. Noteworthy women playwrights writing in the same era as Treadwell are: Zoe Akins Djuna Barnes Rachel Crothers Zona Gale Alice Gerstenberg Susan Glaspell Georgia Douglas Johnson Edna St. Vincent Millay Gertrude Stein Through the use of various 'isms' these playwrights explored new and alternative ways of presenting women's lives in their plays. Treadwell remained widely unknown and un-talked about in the world of theatre scholarship until select feminist scholars resuscitated interest in her works following revivals of Machinal in 1990 by the New York Shakespeare Festival and in 1993 by the Royal National Theatre in London. Resources and further reading The majority of Treadwell's works are stored at the University of Arizona Library Special Collections and the rest at The Billy Rose Theatre Collection at the New York Public Library.
