• Jane Addams founded Hull-House in 1889, a social settlement to improve conditions in a poor immigrant neighborhood in Chicago, then expanded her efforts nationally. Addams gained international recognition as an advocate of women's rights, pacifism and internationalism, and served as the founding president of the Women's International League for Peace and Freedom. Her work ultimately resulted in protective legislation for women and children.

• Muhammad Yunus revolutionized economics by founding the Grameen Bank, or "village bank," in Bangladesh in 1976 to offer "microloans" to help impoverished people attain economic self-sufficiency through self-employment, a model that has been replicated in 58 countries around the world.
As the actions of these historical figures illustrate, the term "social entrepreneur" may be relatively new, but the phenomenon is not.
