As one of the four members of the inner circle at Hull-House, Julia Lathrop played an instrumental role in the field of social reform for more than fifty years. Working tirelessly for women, children, immigrants and workers, she was the first head of the federal Children's Bureau, an ardent advocate of woman suffrage, and a cultural leader. She was also one of Jane Addams's best friends. My Friend, Julia Lathrop is Addams' lovingly rendered biography of a memorable colleague and confidant.   The memoir reveals a great deal about the influence of Hull-House on the social and political history of the early twentieth century. An introduction by long-time Addams scholar Anne Firor Scott provides a broader account of women's work in voluntary associations.
