The figure of the American theatrical scenic designer first emerged in the early twentieth century. As productions moved away from standardized, painted scenery and toward individualized scenic design, the demand for talented new designers grew. Within decades, scenic designers reinvented themselves as professional artists. They ran their own studios, proudly displayed their names on Broadway playbills, and even appeared in magazine and television profiles. American Scenic Design and Freelance Professionalism tells the history of the field through the figures, institutions, and movements that helped create and shape the profession. Taking a unique sociological approach, theatre scholar David Bisaha examines the work that designers performed outside of theatrical productions. He shows how figures such as Lee Simonson, Norman Bel Geddes, Jo Mielziner, and Donald Oenslager constructed a freelance, professional identity for scenic designers by working within their labor union (United Scenic Artists Local 829), generating self-promotional press, building university curricula, and volunteering in wartime service. However, while new institutions provided autonomy and intellectual property rights for many, women, queer, and Black designers were not always welcome to join the organizations that protected freelance designers interests. Among others, Aline Bernstein, Emeline Roche, Perry Watkins, Peggy Clark, and James Reynolds were excluded from professional groups because of their identities. They nonetheless established themselves among the most successful designers of their time. Their stories expand the history of American scenic design by showing how professionalism won designers substantial benefits, yet also created legacies of exclusion with which American theatre is still reckoning with.
