Context: The W.E.B. Du Bois Boyhood Homesite (or W.E.B. Du Bois Homesite) is a National Historic Landmark in Great Barrington, Massachusetts, commemorating an important location in the life of African American intellectual and civil rights activist W.E.B. Du Bois (1868–1963).  The site contains foundational remnants of the home of Du Bois' grandfather, where Du Bois lived for the first five years of his life.  Du Bois was given the house in 1928, and planned to renovate it, but was unable to do so.  He sold it in 1954 and the house was torn down later that decade.  The site is located on South Egremont Road (state routes 23 and 41), west of the junction with Route 71. The Star of Ethiopia is an American historical pageant written by leading New Negro intellectual, W. E. B. Du Bois in 1911.  Outlining the history of African-Americans throughout time, pageants were held in high regard by Du Bois who felt that Pageants could be utilized best as a form of educational theatre, or as an instructional tool to not only teach African Americans the meaning of their history, but also enlighten whites as to "reveal the negro...as human."  Despite his minimal experience in playwriting, Pageant Movement intellectual W.E.B DuBois composed and constructed for the stage "The Star of Ethiopia" to be presented as an American historical pageant. "The Horizon: A Journal of the Color Line" was a monthly periodical in publication during the years 1907 to 1910.  It was the primary communication outlet for the Niagara Movement, and was edited by African-American editor, scholar and author W. E. B. Du Bois.  The magazine was written primarily by African Americans and addressed many African-American themes.  After the National Association for the Advancement of Colored People (NAACP) was formed, publication ceased as Du Bois turned his attention to the NAACP's magazine, "The Crisis", which he also edited.  Prior to "The Horizon", Du Bois published a comparable magazine, " Moon Illustrated Weekly", which lasted for one year in 1906. W. E. B. Du Bois High School of Environmental Science (officially referred to as W. E. B. Du Bois High School) is a public high school located in northeast Baltimore, Maryland.

Lewis High School. William Edward Burghardt "W. E. B." Du Bois ( ; February 23, 1868 – August 27, 1963) was an American sociologist, historian, civil rights activist, Pan-Africanist, author, writer and editor.  Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community.  After completing graduate work at the University of Berlin and Harvard, where he was the first African American to earn a doctorate, he became a professor of history, sociology and economics at Atlanta University.  Du Bois was one of the co-founders of the National Association for the Advancement of Colored People (NAACP) in 1909. The Philadelphia Negro is a sociological study of African Americans in Philadelphia written by W. E. B. Du Bois.  Commissioned by the University of Pennsylvania and published in 1899 with the intent of identifying social problems present in the African American community.  It was the first sociological case study of a black community in the United States and one of the earliest examples of sociology as a statistically based social science.  Du Bois gathered information for the study in the period between August 1896 and December 1896. Akosua Adoma Owusu (born January 1, 1984) is a Ghanaian-American avant-garde filmmaker and producer whose films have screened worldwide in prestigious film festivals, museums, galleries, universities and microcinemas since 2005.  “Owusu uses various production techniques to visualize a state of "triple consciousness", a term she coined in reference to a central tenet of the sociologist and civil rights activist W. E. B. Du Bois’s landmark text "The Souls of Black Folk" (1903).  Du Bois' double consciousness accounts for the experience of black Americans negotiating a sense of selfhood in the face of discrimination and cultural dislocation.  As part of the first generation in her family to be born in the United States, Owusu extends Du Bois’s concept to speak to the crisis of heritage and assimilation for African expatriates and their US-born children."  Owusu has stated that “instead of ‘Africanizing’ Western stories, I’m interested in reclaiming African history rendering them into what is happening in the present day.” The Du Bois Review: Social Science Research on Race is a peer-reviewed academic journal covering multidisciplinary and multicultural social science research and criticism about race.  The journal was established in 2004 and is published by Cambridge University Press for the W. E. B. Du Bois Institute for African and African American Research at Harvard University.  The journal covers a range of disciplines, including economics, political science, sociology, anthropology, law, communications, public policy, psychology, linguistics, and history. The Souls of Black Folk is a classic work of American literature by W. E. B. Du Bois.  It is a seminal work in the history of sociology, and a cornerstone of African-American literary history. Dark Princess, written by sociologist W. E. B. Du Bois in 1928, is one of his five historical novels.  One of Du Bois's favorite works, the novel explores the beauty of people of color around the world.  This was part of Du Bois' use of fiction to explore his times in a way not possible in non-fiction history.  He expressed fully imagined lives of his characters, using them to explore the richness and beauty of black culture.  The novel was not well received when published.  It was criticized for its expression of eroticism as well as for what some critics thought was a failed attempt at social realism.
