Book excerpt: Lucille Mathurin Mair (née Walrond) made a mammoth contribution to women in Jamaica and across the world. In this biography, Verene Shepherd traces Mair's evolving ideology through her roles as professional historian, wife, mother, mentor, diplomat, national and international civil servant, legislator, and women's rights activist. Mair's tireless commitment to the principles of justice and equality for women guided her work and she particularly sought to centre women of the Global South in the development agenda. The accounts of Mair's myriad and often uncredited contributions at the University of the West Indies, the United Nations, and as a senator in the Government of Jamaica are enhanced by previously unpublished extracts from her notes and personal papers and interviews with her friends and colleagues. Shepherd weaves these sources together to give us a thought-provoking study of the evolution of a rebel woman.
