Dr. Cornelia De Bey (May 26, 1865 - April 3, 1948) was a Progressive Era reformer, homeopathic doctor, Chicago public school administrator, labor advocate, and leader in the women's suffrage movement.
 She worked with the famous Hull House community of social reformers, including Jane Addams, Julia Lathrop, Alice De Wolf Kellogg, and Ellen Gates Starr.
 She advocated for major school administration reform, exposing corruption, advocating for more democratic decision-making, and defending the unionization of teachers.
Jane Addams (September 6, 1860May 21, 1935), known as the "mother" of social work, was a pioneer American settlement activist/reformer, social worker, public philosopher, sociologist, author, and leader in women's suffrage and world peace.
 She co-founded, with Ellen Gates Starr, an early settlement house in the United States, Chicago's Hull House that would later become known as one of the most famous settlement houses in America.
 In an era when presidents such as Theodore Roosevelt and Woodrow Wilson identified themselves as reformers and social activists, Addams was one of the most prominent reformers of the Progressive Era.
 She helped America address and focus on issues that were of concern to mothers, such as the needs of children, local public health, and world peace.
 In her essay “Utilization of Women in City Government,” Jane Addams noted the connection between the workings of government and the household, stating that many departments of government, such as sanitation and the schooling of children, could be traced back to traditional women’s roles in the private sphere.
 Thus, these were matters of which women would have more knowledge than men, so women needed the vote to best voice their opinions.
 She said that if women were to be responsible for cleaning up their communities and making them better places to live, they needed to be able to vote to do so effectively.
 Addams became a role model for middle-class women who volunteered to uplift their communities.
 She is increasingly being recognized as a member of the American pragmatist school of philosophy, and is known by many as the first woman "public philosopher in the history of the United States.
 In 1889 she co-founded Hull House, and in 1920 she was a co-founder for the ACLU.
 In 1931 she became the first American woman to be awarded the Nobel Peace Prize, and is recognized as the founder of the social work profession in the United States.
Ellen Gates Starr (March 19, 1859 – February 10, 1940) was an American social reformer and activist.
 She, along with Jane Addams, founded Chicago's Hull House in 1889.
The Bermondsey Settlement was a settlement house founded in Bermondsey, South-East London, by the Rev'd John Scott Lidgett.
 It was the only Methodist foundation among the settlements that appeared in the late 19th and early 20th century.
 Like other settlement houses it offered social, health and educational services to the poor of its neighbourhood.
 It was particularly concerned with educational matters (Lidgett was a prominent educationist) including music and dance.
 It is noted for the work of one of its residents, Grace Kimmins, in relation to children's play.
 Other notable residents included the radical nonconformist Hugh Price Hughes, Grace Kimmins' husband Charles William Kimmins, English socialist and pacifist Ada Salter, and doctor and political radical Alfred Salter.

Founded in 1894, Third Street Music School is the oldest community school of the arts in the United States and traces its roots to the late 19th-century settlement house movement.
 As part of this settlement movement in which young university graduates "settled" in poor, immigrant communities to improve the quality of life, Third Street originally employed live-in social workers and gave baths to children along with their music lessons.
 It was the unique inspiration of Third Street founder Emilie Wagner to make high quality music instruction the centerpiece of a community settlement house that also provided social services to the immigrant population of the Lower East Side.
