 Ostensibly, Hull House was the first co-educational settlement. Addams recognized the need for male residents so that men in the neighborhood could better relate to Hull House endeavors. However, it was clear to visitors and residents that Hull House was a woman’s space. Hull House boasted some of the era’s great minds and change agents. Alice Hamilton (1869–1970), a physician who trained in Germany and the U.S. and is credited with founding the field of industrial medicine, lived at Hull House for 22 years. She went on to teach at Harvard, becoming a nationally recognized social reformer and peace activist. Julia Lathrop (1858–1932) was a Vassar graduate who, in 1912, after residing at Hull House for 22 years, became the first woman to head a federal agency, the Children’s Bureau, which, in terms of conduct, she modeled after Hull House. Rachel Yarros (1869–1946), a twenty-year resident at Hull House, was also a physician who taught at the University of Illinois. The university created a position for Yarros to recognize her tremendous contribution to social hygiene and sex education. Author and feminist theorist Charlotte Perkins Gilman (1860–1935) was a resident for a short time. Gilman thought highly of Addams but had no stomach for settlement existence amongst the oppressed. However, Gilman’s groundbreaking work on gender and economics likely influenced Addams. Sophonisba Breckinridge (1866–1948) graduated from Wellesley and obtained a Ph.D. in political science and a J.D. from the University of Chicago. Her most significant contribution was in the area of social work education. Edith Abbott (1876–1957) and her sister Grace Abbott (1878–1939) joined Hull-House about the time as Breckinridge (1907). Edith Abbott would obtain a Ph.D. in Political Economy from the University of Chicago, while Grace Abbott earned a Ph.D. from Grand Island College in Nebraska. Edith would have an academic career at the University of Chicago prior to her appointment as Chief of the Children’s Bureau after Julia Lathrop’s departure. Mary Kenney (1864–1943) became a vital labor organizer for Samuel Gompers’ American Federation of Labor and influenced Addams’ sensitivity to the plight of organized labor, something that all progressives did not share. Bessie Abramowitz Hillman, a Russian immigrant who attended classes at Hull House, founded the Amalgamated Clothing Workers of America (ACWA) in 1910 at the age of 20 and guided it for 60 years. Hillman referred to the settlement as “a House of Labor”, and she worked with and admired Addams until the latter’s passing. Another resident who became a significant labor leader was Alzina Stevens. She headed the Dorcas Federal Labor Union and became a member of the Council of Women’s Trade Unions of Chicago. Addams worked with and cultivated numerous labor leaders during this nascent time of the American labor movement. These are only a few of the more well-known residents, but numerous feminists used their Hull House experience as a springboard to careers in social reform or professions of various sorts. Addams engaged the residents of Hull House in conversation and deliberation such that they influenced her thoughts and she theirs.
