Walter Rauschenbusch (1861–1918) was an American theologian and Baptist pastor who taught at the Rochester Theological Seminary. Rauschenbusch was a key figure in the Social Gospel and single tax movements that flourished in the United States during the late 19th and early 20th centuries. He was also the maternal grandfather of the influential philosopher Richard Rorty and the great-grandfather of Paul Raushenbush.
Rauschenbusch's work influenced, among others, Martin Luther King Jr., Desmond Tutu, Lucy Randolph Mason, Reinhold Niebuhr, Norman Thomas, James McClendon, and his grandson, Richard Rorty. Even in the 21st century Rauschenbusch's name is used by certain social-justice ministries in tribute to his life and work, including such groups as the Rauschenbusch Metro Ministries in New York and the Rauschenbusch Center for Spirit and Action in Seattle.
