Maria Montessori was one of Italy's first female physicians, and she developed a groundbreaking educational method based on astute observation of children's behavior while working in one of the poorest neighborhoods in Rome (Gutek 2004; Kramer 1988). As someone who witnessed the extent of injustice experienced by poor women and children particularly, she turned from medicine to focus on education, seeing its potential power for social reform (Gutek 2004). Others have been drawn to the Montessori philosophy, sharing her belief that all children have the potential to become self-motivated, independent, and lifelong learners given an appropriate environment in which to flourish. Marginalized communities in the United States find this inclusivity to be a compelling message, leading to a growing number of public Montessori schools serving disadvantaged children (Debs 2019). The work and influence of Black Montessori educators is less well-known than the stories of their white counterparts, this article profiles three Black pioneers in the field. Before elaborating on the stories of Mae Arlene Gadpaille, Roslyn Williams, and Lenore Gertrude Briggs, Black Montessori pioneers who shared Maria Montessori's belief in the power of education for social justice, the authors first provide background on the Montessori Method, Maria Montessori's early years, and the history of Montessori education in the United States.
