Wangari Maathai was a scholar, writer, environmental activist, human rights champion, and Nobel Prize laureate. In her life and thought, she tenaciously sought to expose the precarious lives of people across a variety of communities: women, rural communities, political prisoners, Kenyans, Africans, and citizens of the global South saddled with the burdens of international debt. She also intervened practically to dismantle the forces that limit people’s access to a dignified life. Wangari Maathai is, without a doubt, a worthy and relevant subject for the latest addition to the series, Voices of Liberation. She was committed to service and felt strongly about the principle of servant leadership, a timely and urgent issue not only for sub-Saharan Africa but, indeed, for the world. Wangari Maathai: Registers of Freedom explores the multiple legacies of her life and offers readers a glimpse into the life and thought of one of the 20th century’s most remarkable woman.
