Many art museums rely upon volunteers, often titled docents, to implement a range of educational offerings, including guided gallery experiences. As such, docents regularly engage visitors more than most museum staff members. A review of literature spanning over a century provides support for an examination of four reoccurring themes within museum education and docent history: uncertain definitions, professionalization, theoretical foundation, and embedded traditions. Subsequently, consideration of the past offers context for examining contemporary museum education programs that develop the capacity of docents as change agents, including offerings during the COVID-19 pandemic and developing inclusive practice through docent education. The chapter concludes with an envisioning of the future for docents within museum education.
