Helen Barrett Montgomery (1861-1934) was a social reformer, a Baptist luminary, and a prominent intellectual of the American women's ecumenical missionary movement. In this definitive biography, Kendal Mobley analyses the intellectual development of a fascinating woman and locates her in the context of her rapidly-changing times. Mobley explores Montgomery's early family influences, her education and spiritual development, and her relationship with other notable individuals of the era, including Susan B Anthony. As Mobley points out, Montgomery believed that Christianity gave women equal spiritual and social status with men. Consequently, she saw 'woman's work for woman' as the cutting edge of a global movement for women's emancipation.
