Where he's from and what made him known
Answer:
William Edward Burghardt Du Bois (W.E.B. Du Bois)
Explanation:
W.E.B. Du Bois was the African-American to earn a Ph.D. from Harvard University, and he applied his expertise in the writing of "The Philadelphia Negro: A Social Study" (1899) and "The Souls of Black Folk" (1903).
Du Bois was the best known spokesperson for African-American rights during the first half of the 20th century. He co-founded the National Association for the Advancement of Colored People (NAACP) in 1909.
The case was about turning Native Americans into US citizens. Boarding schools were made where they would figuratively "kill the indian", that is they would make him denounce his cultural heritage, and they would "save the man", meaning they would turn him into a "civilized" US citizen.
