The political movements and social causes of the turbulent 1920s and 30s are brought to life in this study of the work and times of feminist, socialist, and peace activist Rose Henderson (1871-1937). Her commitment to social justice led to frequent monitoring and repression by the authorities but her contributions to activist thought continue to pose challenges for interpretations of the history of Canada, leftism, labour, and women. In the first biography of Henderson, Peter Campbell provides a broader vision and deeper analysis of the period, drawing together the history of labour and of women's movements in French and English Canada, as well as the rise of the Cooperative Commonwealth Federation and its relationship with the Communist Party. Through analysis of Henderson's ground-breaking ideology Campbell shows that in the interwar years she and her comrades developed a distinctive feminism that differs from that of the first and second waves of feminist thought. A fresh look at the turmoil of the early twentieth century from an eye in the storm, Rose Henderson: A Woman for the People brings well-deserved attention to an influential feminist and leftist.
