Born in Charlestown, Massachusetts, to an Irish father and American mother, Julia Harrington Duff began her career as an educator, teaching in Charlestown for 14 years before her marriage to Dr. John Duff. Her election to the Boston School Committee in 1900 marked a significant milestone for the Irish Catholic community, breaking barriers in a time when women faced significant restrictions in politics. While serving on the committee, Duff promoted educational opportunities for women and supported the establishment of kindergartens and schools for girls. Despite opposition, she worked tirelessly to improve the education system, ensuring that Boston’s children received equal opportunities. Duff’s legacy includes advocating for girls to be admitted to Latin School, the creation of kindergartens, and the updating of textbooks. Her efforts extended beyond her committee work; Duff continued to advocate for women’s rights and educational reforms throughout her life. Her contributions are commemorated on the Boston Women’s Heritage Trail, honoring her role in shaping Boston’s educational landscape.
