Question: This  social justice leadership training school and cultural center was founded in 1932 by an American educator and socialist  famous for its role in what?
Context: The Centro Cultural Gabriela Mistral (GAM) is a cultural center located on 227 Av.  Libertador Bernardo O'Higgins, in Santiago de Chile.  The complex was originally built to serve as the headquarters for the third UNCTAD conference, which was held in Santiago in 1972, and consisted of a convention center and an adjoining 22-stories building.  The building was finished in only 275 days in a significant effort supported by several thousand volunteers.  This effort was part of a major propaganda initiative performed by the socialist government of Salvador Allende, in power between the end of 1970 and September 1973 . After the conference, the building was used as a cultural center until the 1973 Chilean coup d'état.  After the end of the Pinochet regime, it hosted a number of conventions and the adjacent tower became the main building for the Ministry of National Defense.  In early 2006, a fire destroyed parts of the building, which led the government of Michelle Bachelet to rethink the original sense of the building and return it into a cultural center, open to the public.  Adapting the structure of its urban environment, the building takes on the concept of transparency and many artworks from the original design.  The second phase that contains an auditorium with space for more than 2000 is going to start soon. The Highlander Research and Education Center, formerly known as the Highlander Folk School, is a social justice leadership training school and cultural center located in New Market, Tennessee.

Much of the history was documented in the book “Or We’ll All Hang Separately: The Highlander Idea” by Thomas Bledsoe.

It fosters a commitment to service as well as prepares young men and women for leadership roles of mid-level management or higher in the fields of education, government, domestic and international community affairs, social justice, and philanthropy. The Center for Progressive Leadership (CPL) was an American 501(c)(3) non-profit organization providing leadership training for advancing progressive political and policy change.  The organization offered 9-month part-time leadership development trainings for a select group of organizational leaders, future candidates, community organizers, and progressive activists in Arizona, Colorado, Michigan, Ohio, Pennsylvania and Wisconsin.  In 2012, CPL merged with Social Justice Leadership (SJL). Social justice educational leadership emphasizes the belief that all students can and will reach proficiency, without exceptions or excuses, and that schools ought to be organized to advance the equitable learning of all students.  Rather than focusing on one group of students who traditionally struggle, or who traditionally succeed, social justice leaders address the learning needs of all students.  Social justice educational leadership specifically addresses how differences in race, income, language, ability, gender, and sexual orientation influence the design and effectiveness of learning environments.  Social justice leadership draws from inclusive education practices from disability education, but extends the concepts further to support students from diverse groups with a wide range of needs.  Through restructuring staff allocation and assessing student progress through disaggregated data, school leaders strive to create schools with equal access and equitable support for all students. Myles Falls Horton (July 9, 1905 – January 19, 1990) was an American educator, socialist and cofounder of the Highlander Folk School, famous for its role in the Civil Rights Movement (Movement leader James Bevel called Horton "The Father of the Civil Rights Movement").

Thompson, and many others. Studio Gang Architects is an American architecture and urban design practice with offices in Chicago and New York.
