Booker T. Washington (1856-1915) believed in a patient process, not immediately challenging the views of white superiority. He thought that by hard work and perseverance, over time the black community would prove itself equal to whites.
W.E.B. Du Bois (1868-1963) criticized Washington's views, believing that it was wrong to allow any continuance of the idea of white superiority over blacks. He promoted social action and agitation to challenge such views, because as long as whites viewed blacks as unequal, they would never allow actual equality to occur, and oppression of blacks by whites would continue in various forms.
The correct answer should be Teddy Roosevelt because he died because all the others were even born, or they were babies when he died. Either way, he couldn't have hung out with him.
