Who was Léa Roback? And what can we learn from activism? Léa Roback (1903-2000) gained renown for her seven decades of activism in Quebec, particularly championing union rights and women rights. Yet, despite her significant accomplishments no English-language biography exists. In our current geo-political climate, marked by polarization and lack of dialogue, documenting Roback's ability to transcend linguistic, religious, cultural, and class boundaries in pursuit of social justice is inspiring. This biography, based on interviews between Roback and filmmaker Sophie Bissonette, sociologist Nicole Lacelle, journalist Merrily Weisbord and others, promises to engage students, educators in social justice-oriented fields, Equity Studies, Gender Studies, Education Studies, Canadian Studies, Canadian History courses and all those who seek justice and enthusiasm from a life-long human rights activist.
